From front line to home front: a study of secondary traumatization.

While the long-term effects of combat trauma on veterans have been studied extensively, its impact on veterans' wives has yet to be investigated. This study examined the implications of combat-induced psychopathology--wartime combat stress reaction (CSR) and current posttraumatic stress disorder (PTSD)--in a sample of 205 wives of Israeli combat veterans of the 1982 Lebanon war. Results show that both CSR and PTSD were associated with increased psychiatric symptoms in the wives. In addition, current PTSD was particularly found to contribute to impaired social relations among veterans' wives in a broad range of contexts, from inner feelings of loneliness, through impaired marital and family relations, and extending to the wider social network. Implications of these findings for treatment and further research are discussed.     

Teenage depression: a cultural-interpersonal-intrapsychic perspective

The "crossroads families" are caught between old value systems and American mainstream goals. Traditional family and sex-related roles and orientations conflict with those of the new social system. In turn, neither of the teenager's orientations--toward home or toward peer activity--is validated. In the clinical case presented, Anna, at adolescence, wants to relinquish many of her household chores and enter her social world more fully. She needs unconflictual support for such a move. If this does not take place, her autonomous movement represents an unconscious betrayal of her depleted and controlling mother as well as an abandonment of the parental coalition. This leaves her feeling resentful, guilty, and ultimately unlovable. Attitudes marked by helplessness and confusion are thus significant to the depressed affect that brings this teenager into family therapy. Teenagers of non-Hispanic background who enter family therapy reveal gross overlap with teenagers of the Hispanic "crossroads" family model. Here, the family gives mixed messages for homebound and intimate closeness as well as accomplishment in the societal mainstream. A primary difference between ethnic groups involves the freer expressions of anger and pain between husband and wife in the non-Hispanic families. This is not similar to the backgrounds of the more individuated Hispanic teenagers. While more open expressions of anger within the family do indicate higher levels of autonomy, the hostility that is expressed by the parents presents serious complications when this includes "triangulating" the child into the family tension. Here, as cited, the mother often uses her daughter as a confidant and ally at times of severe parental discord. This places additional strain on the child's conflict with separation. Importantly, the daughter experiences renewed rejection and betrayal when the mother "submits" to her spouse. These are significant family processes that heighten mixed messages around autonomy. Milagros, a depressed (more individuated) adolescent, is consistently entangled into her parent's abrasive relationship. Her interpersonal family struggles have become intrapsychic and, ultimately, transferential.     

Premature conclusions about the signal-to-noise ratio in structural equation modeling research: A commentary on Yuan and Fang (2023)

In a recent article published in this journal, Yuan and Fang (British Journal of Mathematical and Statistical Psychology, 2023) suggest comparing structural equation modeling (SEM), also known as covariance-based SEM (CB-SEM), estimated by normal-distribution-based maximum likelihood (NML), to regression analysis with (weighted) composites estimated by least squares (LS) in terms of their signal-to-noise ratio (SNR). They summarize their findings in the statement that “[c]ontrary to the common belief that CB-SEM is the preferred method for the analysis of observational data, this article shows that regression analysis via weighted composites yields parameter estimates with much smaller standard errors, and thus corresponds to greater values of the [SNR].” In our commentary, we show that Yuan and Fang have made several incorrect assumptions and claims. Consequently, we recommend that empirical researchers not base their methodological choice regarding CB-SEM and regression analysis with composites on the findings of Yuan and Fang as these findings are premature and require further research.     

A General Measure of Ecological Behavior1

Measurement of ecological behavior across different domains has been troublesome. The present paper argues that the lack of agreement in measuring general ecological behavior may be due to the measurement approach that is commonly used. An ecological behavior measure should be grounded on a probabilistic measurement approach that takes the important features of ecological behavior into consideration. Such a measure was developed in a survey study of 445 members of 2 Swiss transportation associations. Three types of ecological behavior measures were included: a general measure, 3 multiple-item measures, and 3 single-item measures. Results are controlled for social desirability effects. Reliability, internal consistency, and validity scores indicate that a probabilistic measurement approach can measure general ecological behavior accurately and unidimensionally.     

The impact of social environment and sex on adolescent social values: A comparison of the kibbutz and the city in Israel

The present study compares the effects of two different socialization environments—the Israeli kibbutz and the city—on the social values held by 16-17 year-olds. A total of 352 boys and girls, 195 porn the city and 157 porn the kibbutz, filled out a specially prepared thirteen-item questionnaire on social values. The results revealed the existence of four factors underlying these values: self-oriented concerns (factor 1), other-oriented concerns (factor 2), reliance on innate spiritual capacities (factor 3), reliance on physical and productive capacities (factor 4). Significant differences on factors 1 and 3 were uncovered for the kibbutz and the city subjects, while boys and girls differed significantly on factors 2 and 4. The findings were discussed in light of the differences in educational systems between the kibbutz and the city, and in light of sex-role differences characteristic of Western society in general.     

Individual and Dyadic Coping and Fear of Progression in Mothers and Fathers of Children with Hematologic Cancer

This study investigated the association of individual and dyadic coping strategies with fear of progression (FoP) in mothers and fathers of children with hematologic cancer. Parental couples (N = 44) whose children had been diagnosed with hematologic cancer were recruited at a university hospital and a rehabilitation clinic in Germany between 03/2017 and 08/2017. Data included parents' self-report on FoP (Fear of Progression Questionnaire—parent version, FoP-Q-SF/PR), individual coping (Coping Health Inventory for Parents, CHIP-D), and dyadic coping (Dyadic Coping Inventory, DCI). Statistical analyses were carried out for mothers and fathers individually as well as for parental couples using dyadic data analyses (e.g., actor-partner interdependence model, APIM). Individual and dyadic coping strategies were significantly correlated with FoP in mothers, but not in fathers. Fathers' evaluation of the couple's dyadic coping significantly predicted mothers' FoP. The more frequent use of familial integration (CHIP-D FAM) and maintaining social support (CHIP-D SUP) as well as a better evaluation of their partners' dyadic coping was significantly associated with lower FoP in mothers. Differences in individual and dyadic coping in parental couples were not associated with FoP. Individual and dyadic coping strategies should be addressed in the psychosocial care of mothers and fathers of children with hematologic cancer. Study results support the benefits of involving fathers in psychosocial interventions, for example, in couple-based interventions that acknowledge interpersonal effects of coping on FoP. Future research should further explore coping strategies applied by fathers of children with hematologic cancer for the regulation of FoP.     

To Challenge the Morning Lark and the Night Owl: Using Smartphone Sensing Data to Investigate Day–Night Behaviour Patterns

For decades, day–night patterns in behaviour have been investigated by asking people about their sleep–wake timing, their diurnal activity patterns, and their sleep duration. We demonstrate that the increasing digitalization of lifestyle offers new possibilities for research to investigate day–night patterns and related traits with the help of behavioural data. Using smartphone sensing, we collected in vivo data from 597 participants across several weeks and extracted behavioural day–night pattern indicators. Using this data, we explored three popular research topics. First, we focused on individual differences in day–night patterns by investigating whether ‘morning larks’ and ‘night owls’ manifest in smartphone-sensed behavioural indicators. Second, we examined whether personality traits are related to day–night patterns. Finally, exploring social jetlag, we investigated whether traits and work weekly day–night behaviours influence day–night patterns on weekends. Our findings highlight that behavioural data play an essential role in understanding daily routines and their relations to personality traits. We discuss how psychological research can integrate new behavioural approaches to study personality.     

Toward an alternative representation for disentangling age-associated differences in general and specific cognitive abilities

Much of cognitive aging research concerns whether age-associated differences in various cognitive performances can be accounted for by general explanatory constructs or whether several specific processes are involved. Structural equation models have been proposed to disentangle general and specific age-associated differences in cognitive performance. This article demonstrates that existing methods that employ stepwise procedures run the risk of biasing results toward general resource accounts. An alternative model representation (i.e., the nested factor model) is proposed that affords simultaneous estimation of general and specific effects and is applied to data from the Berlin Aging Study. Using the nested factor model allowed the authors to detect that specific group factors explained 25% of the age-associated variance in addition to the general factor.     

Ontogeny of classical and operant learning behaviors in zebrafish

The performance of developing zebrafish in both classical and operant conditioning assays was tested with a particular focus on the emergence of these learning behaviors during development. Strategically positioned visual cues paired with electroshocks were used in two fully automated assays to investigate both learning paradigms. These allow the evaluation of the behavioral performance of zebrafish continuously throughout development, from larva to adult. We found that learning improves throughout development, starts reliably around week 3, and reaches adult performance levels at week 6. Adult fish quickly learned to perform perfectly, and the expression of the learned behavior is manifestly controlled by vision. The memory is behaviorally expressed in adults for at least 6 h and retrievable for at least 12 h.     

How do people judge risks: Availability heuristic, affect heuristic, or both?

How does the public reckon which risks to be concerned about? The availability heuristic and the affect heuristic are key accounts of how laypeople judge risks. Yet, these two accounts have never been systematically tested against each other, nor have their predictive powers been examined across different measures of the public's risk perception. In two studies, we gauged risk perception in student samples by employing three measures (frequency, value of a statistical life, and perceived risk) and by using a homogeneous (cancer) and a classic set of heterogeneous causes of death. Based on these judgments of risk, we tested precise models of the availability heuristic and the affect heuristic and different definitions of availability and affect. Overall, availability-by-recall, a heuristic that exploits people's direct experience of occurrences of risks in their social network, conformed to people's responses best. We also found direct experience to carry a high degree of ecological validity (and one that clearly surpasses that of affective information). However, the relative impact of affective information (as compared to availability) proved more pronounced in value-of-a-statistical-life and perceived-risk judgments than in risk-frequency judgments. Encounters with risks in the media, in contrast, played a negligible role in people's judgments. Going beyond the assumption of exclusive reliance on either availability or affect, we also found evidence for mechanisms that combine both, either sequentially or in a composite fashion. We conclude with a discussion of policy implications of our results, including how to foster people's risk calibration and the success of education campaigns.
