Background: After military deployment, soldiers are at an increased risk of developing posttraumatic psychiatric disorders. The correlation of personal values with symptoms, however, has not yet been examined

within a military context.

Method: Schwartz’s Portrait Values Questionnaire (PVQ), the Posttraumatic Stress Diagnostic Scale (PDS), and the 11-item version of the Resilience Scale (RS-11) were completed by 117 soldiers of the German Armed

Forces who had recently been deployed to Afghanistan (n �40 undergoing initial psychiatric treatment, n �77 untreated). Results: Logistic regression showed that the value types of hedonism ( �), power ( �), tradition (�), and universalism (�) were significantly correlated with the probability and severity of PTSD and whether the participant was in treatment or not. The effects were partially mediated by the RS-11 scale values.

Conclusions: Value types seem to be associated with psychiatric symptoms in soldiers after deployment. These results could contribute to the further development of therapeutic approaches.

I n recent years, German Armed Forces (Bundeswehr)

soldiers have increasingly sought treatment in

Bundeswehr hospitals for deployment-related psy-

chiatric disorders. The most common diagnosis is post-

traumatic stress disorder (PTSD) (Kowalski et al., 2012;

Zimmermann, Hahne, & Ströhle, 2009). There is also

an increased risk for other symptoms in the military,

such as alcohol dependence or anxiety (Wittchen et al.,

2012). The probability of developing a certain disorder

and the severity of symptoms depend on the distribution

of individual risk and resilience factors as well as on the

distribution of stressful experiences during deployment,

which have shown to have discriminant validity when

it comes to symptoms (Dias, Sales, Cardoso & Kleber,

2014; Pietrzak, Whealin, Stotzer, Goldstein, & Southwick,

2011).

Risk and resilience factors can include characteristics

of the values and norms of traumatized persons (Litz

et al., 2009; Siegel & Zimmermann, 2010), although this

dimension has not yet been included as complementary

diagnostic criteria for PTSD in either the ICD-10 or the

DSM-V.

Research on this topic has been very limited. Thus far,

studies have focused on associations between posttrau-

matic symptoms and personal values in victims of crime

and people with adjustment disorders following critical

life events. The results have shown intercultural variations

(Maercker et al., 2009; Müller, Forstmeier, Wagner, &

Maercker, 2011). Additional data are available on the

impact of values on addictions (Dollinger & Kobayashi,

2003; Galdós & Sánchez, 2010).

No empirical studies on personal value orientations

and psychiatric symptoms have been conducted within

the military, even though the well-defined and time-

limited stressors of out-of-area deployment provide ideal

scientific conditions.

The small number of available studies is surprising,

considering that the concepts of individual values and

their effects on attitudes and behavioral patterns have

been a matter of scientific interest since the 1950s

(Kluckhohn, 1951; Rokeach, 1973). Existing approaches

have gained new impulses from Schwartz’s work and

from his ‘‘Theory of Basic Human Values’’ (Schwartz,

1992). Schwartz described values as: ‘‘desirable, trans-

situational goals, varying in importance, that serve as

guiding principles in the life of a person or other social

entity.’’ On the basis of associated motivational goals, he

defined 10 interrelated value types (Table 1). These values

feature either corresponding or contradictory motiva-

tions that are connected with specific consequences for

activities. Interest in change and new experiences, which

is an aspect of the ‘‘stimulation (ST)’’ value, will most

likely not go hand in hand with ‘‘tradition (TR)’’ and

its associated interest in conservation of customs and

habits. ‘‘Conformity’’ and ‘‘TR,’’ in contrast, both lead to

an increased desire to fulfill external expectations. Such

considerations have led to a circumplex model of values,

representing a motivational continuum (Fig. 1) in which

adjacent values are similar, while opposite values tend to

contrast each other (Hinz, Brähler, Schmidt, & Albani,

2005).

More than 200 studies in 60 countries have confirmed

the 10 value types and their circumplex structure

(Schwartz et al., 2001). There have also been several

approaches in which individual values have been

grouped. Schwartz had already divided the values into

four second-order value types (Fig. 1): openness to

change; self-enhancement; self-transcendence; and con-

servation (Schwartz, 2003). Maercker suggested dif-

ferentiating between ‘‘traditional’’ and ‘‘modern’’ values

and found discriminant validity for both groups in the

severity of symptoms of PTSD (Maercker et al., 2009;

Müller et al., 2011).

Genetic and environmental factors have been identified

in the development of different values. The question

of whether values represent a time-stable disposition to

personality structures or whether they are subject to

environmental influences, such as military deployments,

has not been finally answered, however (Schermer,

Feather, Zhu, & Martin, 2008). The test�retest stability of value assessment has generally been high in recent

studies but has also shown a sensitivity to life events that

has had a limited yet significant impact on value changes.

This effect has been greater than the impact of age (Bardi,

Lee, Hofmann-Towfigh & Soutar, 2009).

The availability and acceptance of social support as

well as the capability or willingness to articulate emotions

or talk about symptoms could be possible links between

values and the development of psychiatric symptoms,

such as adjustment disorders, grief reactions, and PTSD

(Brewin, Andrews, & Valentine, 2000; Maercker et al.,

2009; Müller et al., 2011).

Furthermore, personal resilience, which has been

examined in recent studies as a moderating variable for

mental health in the military and in civilian life, might

also be associated with values in this regard (Maercker,

Gäbler, Schützwohl, O’Neil, & Müller, 2013; Sleijpen,

June ter Heide, Mooren, Boeije, & Kleber, 2013; Streb,

Häller, & Michael, 2013). According to Werner (1993,

2012) as well Noeker and Petermann (2008), resilient

people are able to adapt to adverse, often traumatic

environments, resulting in healthy long-term psychologi-

cal functioning and better developmental outcomes.

Resilience is enhanced by adaptive systems on four dif-

ferent levels: personal competencies (coping strategies,

self-regulation, motivation, learning); family systems

(attachment, parent�child interaction, parenting); re- sources of social networks (school, peers); and society

and culture (norms, values) (Hampel & Petermann,

2006).

Outside the military, personal values have started to be

integrated into psychotherapeutic methods over the last

few years, and study results have also provided insight

into the role of values in the development of diseases.

Fegg et al. (2010) were able to strengthen personal values

in clinical patients with carcinoma, who subsequently

reported an increased sense of meaning in life and quality

of life. Additional findings have suggested that a value-

based psychotherapeutic approach could facilitate the

development of emotional self-regulation (Fujita & Han,

2009).

Within the Bundeswehr, efforts have recently been

made to incorporate changes in values and feelings of

guilt and shame into traumatherapeutic methods. Pilot

studies have indicated that, for patients with deployment

experience, behavioral group therapy seems to be an

appropriate setting in which to address these complex

issues because group coherence makes it easier to

verbalize and endure associated emotions (Alliger-Horn

& Zimmermann, 2010).

A prerequisite for any treatment, however, is the

interest of soldiers in receiving help, which seems to be

dependent on attitudes toward mental health services

and unit stigma (Brown, Creel, Engel, Herell, & Hoge,

2011). These factors might also be dependent on personal

values. The issue is especially relevant since a recent study

has shown that only 50% of interviewed German soldiers

were seeking any sort of counseling for PTSD after de-

ployment to Afghanistan and only 20% were in psychia-

tric treatment (Wittchen et al., 2012).

Therefore, the aim of this study was to determine

characteristic value types in Bundeswehr soldiers after

deployment to Afghanistan and their correlation with the

prevalence and severity of PTSD and on the willingness

of soldiers to undergo treatment. Based on the small

amount of existing data, it was hypothesized that certain

value types would be associated with decreased (modern

values) or increased (traditional values) frequency and

symptom severity of PTSD in soldiers after deployment.

Values are part of the resilience construct and thus

resilience might be a mediating variable to explain the

associations. A mediation analysis should be performed

separately for prevalence and severity of PTSD as both

dimensions might lead to different views on the planning

of therapeutic resources and processes. As values are

also connected to perceived social support and fear of

stigma, they might be predictors of interest in psychiatric

treatment.

Method

Participants The participants in this study were 117 Bundeswehr

soldiers who had returned from their deployment to

Afghanistan within the previous 12 months. Power

analyses had revealed that 120 participants would be

necessary in a multiple linear regression analysis [severity

of PTSD] to reach an effect size of f �0.4 (large effect, Cohen’s f2 �0.167) with a probability of 97%. This calculation was based on the hypothesis that three values

would be identified as a predictor to increase the explana-

tory power of the model by 10% in addition to the RS-11

(30%). Nine women and 108 men with an average age

of 28.8 years (SD �6.8) participated. Of those 117 soldiers, 77 had not undergone psychiatric treatment since

their return. Forty participants were assessed at the very

beginning of outpatient or inpatient treatment for deploy-

ment-related mental illness at the Bundeswehr hospital

in Berlin. PTSD was the primary diagnosis in 24 subjects,

while a further six were diagnosed with adjustment

disorder, five with depression, two with addictive disorders

and three with other psychiatric illness.

Instruments and procedures The participants completed the Portrait Values Ques-

tionnaire (PVQ) (according to Schwartz, 2003; Schwartz

et al., 2001), the Posttraumatic Stress Diagnostic Scale

(PDS) (Foa, Cashman, Jaycox, & Perry, 1997), and the

11-item German version of the Resilience Scale (RS-

11) (Wagnild & Young, 1993). The questions asked in

the testing sessions covered the 4 weeks preceding the

evaluation.

The primary diagnoses of the clinical patients were

based on clinical interviews with medical doctors or

clinical psychologists with at least 5 years of training in

clinical psychiatry in accordance with the WHO Interna-

tional Classification of Diseases, tenth edition (ICD-10).

The diagnoses were re-evaluated and confirmed by two

study researchers based on the patient charts. As some

of the first study participants expressed concerns that

they might be recognizable by their answers, detailed

socio-biographical information, such as rank, unit and

education, was no longer collected in order to prevent

aggravation or dissimulation of symptoms. Types of

trauma exposure were also not determined in this study.

In 40 items, the PVQ (Schwartz et al., 2001, 2003)

measures the degree to which each one of 10 basic values

(Table 1) is present, with two to six items attributed to

each value type. In two sentences each, these items briefly

portray a fictional person and outline a perception or

Personal values in soldiers after deployment

action that is associated with a particular value. Respon-

dents can rate their similarity to the person described on

a scale from 1 (not similar at all) to 6 (very similar). The

responses to the portraits of each value type are averaged.

The PVQ attained a Cronbach’s alpha of 0.55 (median of

the value scales) in the validation studies (Schwartz, 2003;

Schwartz et al., 2001), in other investigations it reached

0.70�0.74 (Maercker et al., 2009). In this study sample, the median Cronbach’s alpha was 0.54 (median of the

value scales). It was used despite this low level because

most of the subscales showed acceptable or good values.

Test�retest reliability fell in the range of 0.66�0.88. Pearson’s correlation between Schwartz Value Survey

(SVS) and PVQ was 0.95 (pB0.001).

The PDS was developed by Foa in the early 1990s as

a screening instrument for diagnosing PTSD with high

specificity (82% consistency with the Structured Clinical

Interview of Diagnoses (SCID) diagnostic interview for

the Diagnostic and Statistical Manual of Diseases (DSM)).

The cut-off for detecting PTSD used in this study was

27 on the global score. The severity of symptoms is mea-

sured both in an overall score as well as in subscores

relating to the symptom clusters of intrusion, hyperar-

ousal, and avoidance. In evaluation studies, it yielded

satisfactory results in terms of test quality with a

Cronbach’s alpha of 0.92 and a test�retest reliability of kappa �0.74 (Foa et al., 1997).

The 11-item version of the RS by Wagnild and Young

(1993) was translated into German in 2004 (RS-11).

The original version with 25 items included two subscales

that covered the fields of ‘‘Personal Competence’’ (self-

reliance, independence, mastery, resourcefulness, perse-

verance) and ‘‘Acceptance of Self and Life’’ (adaptability,

tolerance, a flexible perception of the self, and life). In

the German short version, these items were condensed into

11 items in a unidimensional model without loss of validity

(Schumacher, Leppert, Gunzelmann, Strauß, & Brähler,

2004). Evaluation by means of a population-based sample

(N �2,031) showed item-total correlations ranging from ris �0.50 to 0.75 and good internal consistency, with a Cronbach’s alpha of 0.91 (Schumacher et al., 2004).

Statistical analysis Schwartz’s 10 value types were the primary explanatory

variables of the study. The normal distribution assump-

tion had to be confirmed before parametric evaluation

methods could be applied. The Kolmogorov-Smirnov test

did not show any abnormalities in the residuals of the

10 value types (i.e., after deduction of the group average

values); it only revealed significant scores for self-direction

(SD) and universalism (UN) (p �0.022 and 0.032, res- pectively), which implied a possible non-normal distribu-

tion. Deviation from normal distribution, however, was

not high, so normal distribution was assumed for all of

the value types in the following analysis.

Multiple logistic regression was performed in the

whole sample (including both treatment and non-treat-

ment groups) with the response variable of presence of

PTSD in the PDS scale, while multiple linear regression

was performed with the response variable of PTSD

severity. Value types, RS-11 total score, age, and sex

were explanatory variables. In a step-by-step approach,

value types (in the order of their predictive value) and

RS-11 total score were successively incorporated into the

model. Afterwards a mediation analysis was performed

with the RS-11 sum scale values as mediator and value

types as predictor. Standardization followed MacKinnon

and Dwyer (1993). For indirect effects the Sobel test was

used.

The average age of the group that underwent treatment

differed significantly from that of the group that did not

undergo treatment (t(115) �3.21; p �0.002). In addition, age had a significant impact on the soldiers’ attitudes

towards ST, UN, benevolence (BE) and security (SE).

As a consequence, age had to be controlled for in the

main evaluations. The results were also controlled for sex.

Multivariate analysis of variance was performed to

compare the treatment group and the non-treatment

group.

All of the participants provided informed consent.

The study was approved by the ethics committee of the

Charité University Berlin (no. EA1/203/13).

Results The predominant value types of the whole sample

were BE (M �3.66), SD (M �3.63), SE (M �3.35), conformity (M �3.28), and hedonism (HE) (M �3.27) (Table 1).

Table 2 shows the Pearson correlations between the

value types and age, resilience and PTSD severity.

The regression model used to predict the probability

of PTSD, developed from the value types while taking

into account age and sex (Table 3), showed power (PO),

HE (both negative ( �) correlation), and UN (positive (�) correlation) to have significant effects. This model classified 83.5% of the subjects correctly as to the

presence of PTSD. The variables UN and TR showed a

strong correlation (Pearson’s r �0.60, pB0.001). In fact, TR could have replaced UN in the model without

a significant decrease in the quality of the model. If

both UN and TR were included in the model at the same

time, however, neither was significant.

If the RS-11 was included in the model, HE was no

longer significant but UN (�) and power ( �) remained significant. A total of 86.2% of the subjects were correctly

classified, thus making the model that takes resilience

into account better than the one that did not include

RS-11.

A mediation analysis (Baron & Kenny, 1986;

MacKinnon & Dwyer, 1993) with UN, PO, and HE

as predictors and resilience as mediator (controlled for

age and sex) showed that the effect of UN on PTSD

probability was mostly direct, the correlation of PO was

roughly two thirds direct, while the one of HE was

equal parts directly and indirectly (Table 4).

The severity of PTSD (Table 5) was significantly

correlated with HE ( �). With RS-11 included in the model, the significance of HE was retained, with an

additional significant effect of SD (�). Again, the explanatory power of the model was increased by the

inclusion of resilience.

Mediation analysis showed that the effect of HE on

PTSD severity was almost equal parts direct and indirect,

while the effect of SD was inconsistent: direct and indirect

effects operated in opposite directions (Table 6).

The differences in value orientations established be-

tween the group receiving initial treatment and the

untreated group were, on the whole, significant (Pillai’s

trace: F(10.104) �2.72; p �0.005; controlled for age/sex). The two groups also differed significantly in resilience

scores on the RS-11 scale, with the group not in therapy

achieving a higher score (M �63.52; SD �7.47) than the therapy group at the beginning of treatment (M �50.51; SD �12.87; t(114) �6.88; pB0.001). Differences be- tween the groups (after correction of the significance

level for 10 post-hoc tests to pB0.005) were particularly

significant for the value types of power (PO) and HE. The

group that did not receive treatment achieved higher

scores for these values than the group that did (Table 7).

Discussion The objective of this study was to describe the value types

of Bundeswehr soldiers after deployment to Afghanistan

and to identify associations with the probability and

severity of posttraumatic stress as well as with psychiatric

treatment readiness. Given the cross-sectional design of

the study, the results must be interpreted with caution,

but there are currently no empirical studies in which

value types and their relationships with mental health

were evaluated in a military context.

The predominant value types of this sample were,

starting with the highest mean rating, BE, SD, SE,Table 3. Regression model for probability of PTSD

Personal values in soldiers after deployment

conformity, and HE (Table 1). A telephone survey of

1,078 participants randomly selected from the German

adult population showed different priorities: SD, UN,

BE, SE, and HE (Schoen, 2009).

Thus, the results suggest differences in value orien-

tations of soldiers compared to the general population.

It remains unclear, however, if the differences are due to

Bundeswehr recruitment processes, to military socializa-

tion or to deployment-related experiences. This requires

further study.

HE was negatively correlated with the probability and

severity of PTSD in the analysis of the complete study

sample. Similarly, power (PO) was negatively correlated

with the probability of PTSD. As expected, TR and UN,

which lie opposite to HE and power in the circular

structure of Schwartz’s value model, had a contrary effect

on probability.

Overall, values were weaker than resilience in multi-

variate prediction of symptom probability and severity.

In the mediation analysis, the effect of UN on PTSD

probability was mostly direct, the one of PO was roughly

two thirds direct, and of HE was equal parts direct and

indirect (mediated by RS-11 scale values). The effect of

HE on PTSD severity was almost equal parts direct and

indirect, while the effect of SD was inconsistent: direct

and indirect effects operated in opposite directions.

It seems interesting that probability and severity of

PTSD were differently correlated with values. UN and

power affected probability but not severity, thus indicat-

ing that values might have specific effects in the percep-

tion of stress-related symptoms.

All in all, the results concerning SD and power have

limited value due to the low Cronbach’s alpha (both

0.54) of these subscales. By contrast, HE and UN had

acceptable or good values (0.88/0.75).

The influence of resilience on military-related or

civilian posttraumatic symptoms has been proven in

numerous studies (Maercker et al., 2013; Streb et al.,

2013). It has not yet been investigated, however, how the

concepts of values and resilience are connected. Both

could represent time-stable personality traits (Noeker &

Petermann, 2008; Werner, 2012) that are directly related.

In contrast, it can be hypothesized that values might

change due to numerous stressful or traumatic life events,

such as deployment experiences (Bardi et al., 2009;

Wittchen et al., 2012). Longitudinal studies, with mea-

surements before and after deployment, might help

clarify this question, but such studies have not been

performed to date.

The impact of values as time-stable personality traits

on mental health might be explained by subsequent

tendencies in how people address mental health issues

and how people perceive social support. In accordance

with our results, Maercker et al. (2009) found a sig-

nificant negative correlation between so-called ‘‘modern’’

values (achievement, HE, ST) and the severity of PTSD

in German victims of violence. Conversely, ‘‘traditional’’

values (conformity, BE, TR) were linked to an exacerba-

tion of symptoms. The authors explained this finding

with a perceived improvement in the social acceptance of

victimhood that is associated with these modern values,

which results in less fear of isolation and ostracism.

Other studies have described mentally ill subjects with

traditional values as feeling a stronger sense of social

ostracism and guilt about their symptoms (Bennet-

Herbert & Dunkel-Schetter, 1992). These associations

could explain our study results, too, particularly with

respect to HE and TR.

The results, however, have been replicable only to a

limited extent. In an elderly Swiss population sample,

traditional values were associated with less stress result-

ing from adjustment disorders and grieving processes

(Müller et al., 2011). The inconsistency of findings was

evident in another study of 275 subjects from various

countries, in which the value types of ST and HE and,

surprisingly, BE were correlated with the perception of

better social support (Goodwin, Costa, & Adonu, 2004).

In addition, the described correlation between values

and perceived social support cannot explain why HE

and power were less pronounced in our study group

of subjects receiving psychiatric treatment. A similarly

unexpected association in a military context was reported

by Brown et al. (2011), who found that greater interest in

therapy was associated with higher fear of unit stigma.

Due to these contradictory findings, additional ratio-

nales should be discussed: it seems possible that values

like UN go hand in hand with more pronounced empathy

for the fates of others (Schwartz, 1996) and thus may lead

to an increase in suffering from posttraumatic memories

and symptoms. A common part of traumatogenic ex-

periences in a military operation is witnessing serious

harm to the civilian population but also to fellow soldiers

in the course of combat action. In a prevalence study of

the Bundeswehr (Wittchen et al., 2012), soldiers deployed

to Afghanistan in 2009/2010 reported that they saw de-

stroyed houses and villages (76.4%), encountered injured

women and children without being able to help (32%),

saw dead and injured fellow soldiers (31.3%, with 1.9%

experiencing the incident in question in close proximity),

dead bodies and body parts (29.6%) and witnessed vio-

lence among the local population (21%). A clear differ-

entiation of deployment experiences, which would have

served to correlate them to value types, was, however,

not part of this study.

The effect of power might be due to a negative

item correlation with PTSD symptoms, as feelings of

helplessness and powerlessness are part of the traumatic

experience according to DSM-IV and ICD-10 diagnostic

classifications. These topics demand further research.

There have been only a few findings that support the

hypothesis of a change in personal values due to military

deployment. In a civilian study, life events had a significant

impact on test�retest reliability of value measurement in a longitudinal assessment of an adult study population

(Bardi et al., 2009).

This concept would correspond with the results on

Posttraumatic Growth (Tedeschi & Calhoun, 2004). Post-

traumatic Growth includes five dimensions that underlie

on-going positive changes after traumatic experiences

and might show significant overlap with values: greater

appreciation of life and a changed sense of priorities,

warmer, more intimate relationships with others, greater

sense of personal strength, recognition of new possibilities

or paths for one’s life and spiritual development.

Although the questions regarding the time-stability

of values and the possible impact of external influences,

such as military deployment or therapeutic approaches,

have not yet been answered, the first clinical experiences

have been gathered based on our study results. These

experiences have suggested that interventions aimed at

UN or TR as personal values and subsequent feelings

of failure and related guilt after traumatic stress might

have relieving effects and could help patients accept

values in line with a critical but fair self-assessment.

Thus value orientations might become an important

part of psychotraumatological treatment settings in the

future (Zimmermann, Biesold, Barre, & Lanczik, 2007).

Accordingly, the affirmation of personal values in par-

ticipants of an experimental study design, using the

Trier Social Stress Test, led to a reduced stress reaction,

measured as cortisol response compared to controls

(Creswell et al., 2005).

While the lack of impact of sex on the statistical

model was expected, the results of age were surprising.

In international surveys, sex has also been found to have

little correlations with value types (Schwartz et al., 2001).

Age, however, has been shown to be significantly cor-

related with the extent to which any one value type was

pronounced (Schwartz et al., 2001). The homogenous

age structure of this sample with a low rate of female

participants might explain the differences.

Limitations This study was limited in its predictive power due to its

cross-sectional design, which did not allow us to establish

clear causal attributions of deployment-related stressors,

changes in values, and psychiatric illness. The small

sample size was another limitation. Inferences about

the prevalence of mental illness were also problematic,

as only self-report measurements were obtained and no

standardized diagnostic interviews were conducted as

part of this study, although the PDS corresponds quite

well to such interviews.

The results of this study are not readily applicable to

other subject groups, such as policemen and firefighters,

because the development of values is closely linked to the

subjects’ cultural environment, socio-demographic fac-

tors, work environment, and experiences to be processed.

Nevertheless, these occupational groups also face extreme

work-related stress and their hierarchical structures with

predominantly male staff suggest further similarities.

To our knowledge, there have not been any studies in

these populations either.

Conclusions Despite its methodological limitations, this study suggests

that there are associations between value types (especially

Personal values in soldiers after deployment

HE, power, TR, and UN) and mental health as well as

treatment readiness in soldiers after military deployment.

Further research is required to determine other influen-

cing variables, such as perceived stigma and resilience,

and whether these results might be applicable to forces

with other types of stress, such as police forces and fire-

fighters. Such research should be longitudinal in design,

with measurements before and after deployment, and

should take the nature of stressful events experienced into

account.

As cultural aspects beyond the direct military environ-

ment might influence the development of values, other

armed forces should also conduct similar studies to allow

for comparisons. Such an international comparison could

result in additional insights into the development of

values and relevant influencing factors.

A possible suggestion based on the basis of the data

gathered here would be that addressing values could be

beneficial in clinical psychotraumatology settings in the

military work environment.

Conflict of interest and funding

There is no conflict of interest in the present study for any
