Posttraumatic Stress Disorder Symptom Clusters and the Interpersonal Theory of Suicide in a Large Military Sample

Prior studies examining posttraumatic stress disorder (PTSD) symptom clusters and the components of the interpersonal theory of suicide (ITS) have yielded mixed results, likely stemming in part from the use of divergent samples and measurement techniques. This study aimed to expand on these findings by utilizing a large military sample, gold standard ITS measures, and multiple PTSD factor structures. Utilizing a sample of 935 military personnel, hierarchical multiple regression analyses were used to test the association between PTSD symptom clusters and the ITS variables. Additionally, we tested for indirect effects of PTSD symptom clusters on suicidal ideation through thwarted belongingness, conditional on levels of perceived burdensomeness. Results indicated that numbing symptoms are positively associated with both perceived burdensomeness and thwarted belongingness and hyperarousal symptoms (dysphoric arousal in the 5‐factor model) are positively associated with thwarted belongingness. Results also indicated that hyperarousal symptoms (anxious arousal in the 5‐factor model) were positively associated with fearlessness about death. The positive association between PTSD symptom clusters and suicidal ideation was inconsistent and modest, with mixed support for the ITS model. Overall, these results provide further clarity regarding the association between specific PTSD symptom clusters and suicide risk factors.     

Preliminary examination of psychometric properties of the Korean version of the Specific Interpersonal Trust Scale

The purpose of this study was to examine the psychometric properties of the Specific Interpersonal Trust scale of Johnson-George and Swap in Korean samples as a part of the process of providing an exemplary tool for intercultural studies of trust. A translated version of the original scale was administered to 337 university students (157 males, 180 females) in Seoul, Korea. Data were subjected to a principal components analysis and a confirmatory factor analysis. In principal components analysis for the Korean sample (n= 167), three factors were identified and labeled: Overall Trust (Cronbach alpha= .89), Emotional Trust (Cronbach alpha=.88), and Reliableness (Cronbach a=.84). A confirmatory factor analysis (n= 170) showed that the three-factor model was valid for the sample (chi(2)/df= 1.78, RMR= .06, RMSEA= .07, TLI=.92, CFI=.93). Internal consistency reliability and factorial validity were satisfactory in the case of the Korean sample. The Korean version of the Specific Interpersonal Trust Scale made good use of three factors of trust and appeared to be valid without sex differences, while the original scale distinguished the Males subscale from the Females subscale. Implications and limitations of this study were discussed.

Does Cooperation in the Laboratory Reflect the Operation of a Broad Trait?

The Dictator Game, a face valid measure of altruism, and the Trust Game, a face valid measure of trust and trustworthiness, are among the most widely used behavioural measures in human cooperation research. Researchers have observed considerable covariation among these and other economic games, leading them to assert that there exists a general human propensity to cooperate that varies in strength across individuals and manifests itself across a variety of social settings. To formalize this hypothesis, we created an S‐1 bifactor model using 276 participants' Dictator Game and Trust Game decisions. The general factor had significant, moderate associations with self‐reported and peer‐reported altruism, trust, and trustworthiness. Thus, the positive covariation among economic games is not reducible to the games' shared situational features. Two hundred participants returned for a second session. The general factor based on Dictator Game and Trust Game decisions from this session did not significantly predict self‐reported and peer‐reported cooperation, suggesting that experience with economic games causes them to measure different traits from those that are reflected in self‐assessments and peer‐assessments of cooperativeness. © 2018 European Association of Personality Psychology     

A preliminary scale for assessing attitudes toward homosexuals in the military

This paper reports a factor analytical study of responses to statements of attitudes concerning lesbians and gay men in the military by 72 23.4-yr.-old members of the U.S. Marine Corps Reserve. Using exploratory factor analysis with an oblique rotation four factors were found which accounted for 64.9% of the total common variance. A factor labeled Trust accounted for 40.6% of the common variance, Comfort accounted for 8.7%, Acceptance accounted for 8.2%, and the fourth factor, Threat, accounted for 7.5%. Cronbach a ranged from .63 to .78. Validity was .75 when scores were correlated with those on the Attitudes Toward Lesbians and Gay Men scale, supporting the 4-factor interpretation. It is recommended that additional factor analyses be performed to further investigate the validity of the four factors and that of the entire scale.     

Use of factor analysis in the study of alcohol-induced strategy changes in skilled performance on a soccer test

The present study was designed to examine how skilled behaviour changes under the effects of two doses of alcohol (0.5 gm/kg and 1 gm/kg). A battery of perceptual-motor reference tests, together with the criterion test of a soccer slalom were given a sample of 48 male volunteers to show how performance strategies changed across the different experimental conditions. Analysis indicated little change between effects of placebo and the lower dose but some change in the composition of performance between placebo and the 1 gm/kg dose. This finding supports further use of factor analysis in the study of skilled behaviour.     

THE CONSTANCY OF STRUCTURE OF PERCEIVED PARENTAL REARING STYLE IN GREEK AND SPANISH SUBJECTS AS COMPARED WITH THE DUTCH

To be able to contribute to the cross-cultural study of child-rearing practices and psychopathology, this study sought to examine the cross-national generalizability of parental rearing constructs by analyzing self-report data on the EMBU, an instrument designed to assess memories of one's parents' rearing behavior. Of the four primary factors identified originally with Dutch individuals, namely Rejection, Emotional Warmth, Overprotection and Favoring Subject, the first three were replicated in a similar form in a Greek and a Spanish sample of normal research volunteers. Other properties of the factors, their corresponding scales, and the items constituting the scales were such that it would be warranted to carry out mean scale level or pattern comparisons between subjects from the respective countries on the three constructs evidencing cross-national constancy. Scale-level factor analysis of these constructs produced identical two- factor compositions (CARE and PROTECTION) across the Greek, the Spanish and the Dutch samples which further supported this conclusion.     

Developing a scale of self-efficacy in personal relationships for adolescents

This study developed a scale of self-efficacy in personal relationships for adolescents and examined its reliability and the validity. The 40 items assessing tendencies theoretically linked to self-efficacy in personal relationships were administered to 344 junior and high school students. 207 high school students also were administered the Shimoda Personality Inventory. Three factors (Self-confidence in Personal Relationship, Trust in Friends, and Trust by Friends) were extracted by principal components analysis. The coefficient alpha reliabilities of these subscales were .90, .89. and .87. The validity was supported by correlations between the Total score of self-efficacy and the SPI subscales of Autistic trait -.53, Nervous Character trait -.13, Self-uncertain trait -.39, and Syntonic trait .57.     

High-performance work systems and occupational safety

Two studies were conducted investigating the relationship between high-performance work systems (HPWS) and occupational safety. In Study 1, data were obtained from company human resource and safety directors across 138 organizations. LISREL VIII results showed that an HPWS was positively related to occupational safety at the organizational level. Study 2 used data from 189 front-line employees in 2 organizations. Trust in management and perceived safety climate were found to mediate the relationship between an HPWS and safety performance measured in terms of personal-safety orientation (i.e., safety knowledge, safety motivation, safety compliance, and safety initiative) and safety incidents (i.e., injuries requiring first aid and near misses). These 2 studies provide confirmation of the important role organizational factors play in ensuring worker safety.     

Score comparability of a state mathematics assessment across students with and without reading accommodations

This study investigated the factorial invariance of a fourth-grade state mathematics assessment across groups of general education students and students with learning disabilities with and without reading accommodations. Confirmatory factor analysis was used to assess the fit of a 2-factor model to each of the 3 groups. In addition to the overall fit of this model, several levels of constraint were investigated. Invariance across the 3 groups was supported for factor loadings and intercepts. However, invariance of the factor covariances across the general education group and the groups of students with learning disabilities was not supported. Because of the implications for aggregating reported scores, further research is needed into the relationship between the factors in the different groups.     

CATTELL AND EYSENCK FACTOR SCORES RELATED TO COMREY PERSONALITY FACTORS

The Eysenck Personality Inventory, the Cattell 16 PF Inventory, and the Comrey Personality Inventory were administered to 272 volunteers. Eysenck and Cattell factor scores were correlated with scores over homogeneous item groups (FHIDs) which define the Comrey test factors. This matrix was factor analyzed to relate the Eysenck and Cattell factor scores to the factor structure underlying the Comrey test. The Eysenck Neuroticism, Comrey Neuroticism, and Cattell second-order Anxiety factors appeared to match. The Eysenck Introversion and the Comrey Shyness factors also matched. The 16 Cattell primary factors overlapped but did not match with the Comrey factors.     

The Assessment of Trust Orientation

The development of the Trust Inventory, a 40-item measure of trust in generalized others (Generalized Trust) and romantic partners (Partner Trust) is described. A third conceptualization of trust in friends and family members (Network Trust) is also discussed College students (N = 1,229) participated in five stages of test construction and validation. Results indicated that the Trust Inventory scales are reliable, both internally and temporally, and that the Partner Trust and Generalized Trust Scales demonstrate both concurrent and construct validity. The resulting inventory is unique in its capacity to assess these types of trust simultaneously. Evidence supporting the discriminant validity of the Network Trust was mixed, whereas factor analytic treatments of Trust Inventory items supported the distinctiveness of Network Trust as compared to Partner and Generalized Trust, the Network Trust Scale correlated to roughly the same degree as the other two scales with several variables of differential theoretical relevance. Thus, little evidence supporting the incremental validity of Network Trust was observed Discussion focuses on the evidence suggesting the validity of interpretations of Generalized and Partner Trust and considers the issue of additional research regarding Network Trust.

Measuring trust in teams: Development and validation of a multifaceted measure of formative and reflective indicators of team trust

This article describes the development and validation of a multidimensional instrument designed to measure trust within teams. Trust is conceptualized as a latent variable resulting from distinct but related (formative) indicators, i.e., propensity to trust and perceived trustworthiness, which lead to (reflective) indicators, i.e., behaviours cooperation and monitoring between team members. The instrument was tested in two different samples. The first sample included 98 hospital professionals (14 teams) and provided data for the exploratory factor analysis of this instrument (Study 1). The second sample included responses from 112 teams (395 individuals) from three social-care institutions and was used to apply confirmatory factor analysis (Study 2). Data attesting to the underlying factor structure, internal homogeneity, construct validity, and consensual power of agreement within teams and discriminant power across teams of the instrument are presented. The final 21-item, four-factor version of this measure demonstrates good psychometric properties, with acceptable levels of reliability and validity. We conclude that the scales form a parsimonious, valid, and efficient instrument to assess trust in teams. Potential applications of this measure in research and practice are described and the implications of these findings for future research are discussed.     

A multivariable analysis of spatial abilities by sex

This article presents a series of studies investigating the influence of experimental factors and the personological variables of age and sex upon spatial abilities. It was hypothesized that the overall equivocal findings typical of spatial research may be partially due to the use of different factors across studies. The experimental variables of spatial factor, task demands, spatial information type, information-processing mode, and response mode were systematically manipulated across the eight studies. In each individual analysis of data collected in a specific study, no significant main effect sex differences were detected. However, when a meta-analytic review of the studies was conducted, both spatial information dimensionality and information dimensionality × spatial factor assessed proved to be influential on male and female spatial performances. Female performance was superior when the dimensionality of stimulus and response variables was invariant. Males had the advantage when dimensionality crossing was necessitated. The discrepancy between the sexes was particularly dramatic when the spatial orientation factor was tapped.     

Motivational needs of adolescent volunteers

This study investigated the motivational needs of adolescent volunteers. The Volunteer Needs Profile (Francies, 1982) was administered to adolescents in a variety of volunteer settings, and data were examined using factor analysis. While there were similarities between the motivations of adolescent and older volunteers, some important differences were found. The findings are explored in the context of the adolescent developmental stage, and implications are discussed.     

A component analysis of behavioral skills training with volunteers teaching motor skills to individuals with developmental disabilities

This study included a component analysis of behavioral skills training (BST) for teaching volunteers how to use this training method to support individuals with developmental disabilities in a physical education program. In an alternating treatment design embedded within a multiple baseline design across five participants, the number of BST steps that volunteers completed correctly while teaching four motor skills was measured. In the initial training phase, each motor skill was taught to volunteers using a specific component of BST (i.e., instructions, modeling, rehearsal, or feedback). In subsequent training phases, BST components were combined to teach the volunteers the motor skills for which they did not reach a predetermined mastery criterion (a score of four correct responses across two consecutive trials). Maintenance was assessed. Results indicated that individual components of BST alone were sufficient for volunteers to meet the mastery criterion; however, the full BST framework was necessary for skill maintenance. Strengths, limitations, and recommendations for future research are discussed.     

Project Trust: breaking down barriers between middle school children

This paper analyzes the success of a camp retreat weekend called Project Trust involving middle school students and teachers. The goal of the camp is to break down barriers between cliques identified as active in the school. The camp focuses on building team relationships across clique membership and incorporates elements of peace education and conflict resolution. A treatment group (campers) and comparison group (noncampers) were administered an adaptation of the Bogardus Social Distance Test and the Piers-Harris Children's Self-Concept Scale before and after the camp. Attendance was found to lower social distance scores for nine of the ten groups/cliques. Campers also had higher self-concept scores after the retreat.
