Considerations in the choice of interobserver reliability estimates

Two types of interobserver reliability values may be needed in treatment studies in which observers constitute the primary data-acquisition system: trial reliability and the reliability of the composite unit or score which is subsequently analyzed, e.g., daily or weekly session totals. Two approaches to determining interobserver reliability are described: percentage agreement and "correlational" measures of reliability. The interpretation of these estimates, factors affecting their magnitude, and the advantages and limitations of each approach are presented.     

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.     

Getting older and living up to implicit followership theories: Implications for employee psychological health and job attitudes

Age discrimination at work is a widespread destructive phenomenon that often takes subtle forms. Based on negative stereotypes about older employees, we argue that older employees often experience that they are perceived as less ideal followers than younger employees. We propose that older and younger employees do not differ in what they assume their supervisors expect of an ideal follower (implicit followership theories, IFTs). Thus, we hypothesize that older employees perceive that they compare less favorably to their supervisors' IFTs than younger employees (i.e., worse IFT-fit). This should entail lower quality of the relationship between leader and follower (leader-member-exchange, LMX), which, in turn, should have detrimental effects on employees' health (i.e., burnout) and job attitudes (i.e., job satisfaction, turnover intentions, and identification). We tested our model in a field study with 379 employees. Results differed for ideal and counter-ideal follower attributes. Concerning counter-ideal follower attributes (e.g., being incompetent), age had the proposed negative effect on psychological health and job attitudes that mediated through IFT-fit and LMX. Concerning ideal follower attributes (e.g., thinking ahead), older employees expected their supervisors not only to think less of them than of their younger colleagues, but also expected them to have less demanding IFTs—contrary to our expectations. Employee age was negatively related to psychological health and job attitudes, mediated through lower perceived IFTs, worse perceived appraisal of the actual employee and their joint effects on LMX.

Virtual reality: A new track in psychological research

One major challenge of social interaction research is to achieve high experimental control over social interactions to allow for rigorous scientific reasoning. Virtual reality (VR) promises this level of control. Pan and Hamilton guide us with a detailed review on existing and future possibilities and challenges of using VR for social interaction research. Here, we extend the discussion to methodological and practical implications when using VR.     

Effects of procedure and outcome accountability on interview validity

This study tested effects of holding interviewers accountable for either the procedure they follow to make interview judgments (procedure accountability) or the accuracy of their judgments (outcome accountability) on interview validity. Undergraduates (N = 338) simulated employment interviewers in an experiment that crossed 2 levels of procedure accountability with 2 levels of outcome accountability. They watched videotapes of 60 managers answering an interview question and rated the managers on leadership potential. The dependent variable was the correlation between their interview judgments and supervisory ratings of the managers' actual leadership performance on the job. Results showed that procedure accountability increased interview validity and outcome accountability lowered it. Participants' apparent attentiveness fully mediated effects of procedure accountability on interview validity.     

Learning subjective health complaints

Symptom episodes often show a spatio-temporal structure, that is, they occur in a specific context for a certain duration. Repeated experiences may therefore be construed as associative learning trials, in which context elements are turned into predictive cues, triggering anticipatory processes conducive to subjective health complaints. A series of experiments, using inhalations of air enriched with CO2 and external (odors) or internal (mental images) stimuli as cues, is discussed to show that subjective health complaints may occur upon presenting the cue alone. Learned symptoms may be unrelated to bodily responses and easily generalize to new related cues. Better learning occurs to cues with a negative affective valence and in participants scoring high for negative affectivity. Our findings are relevant to the understanding of medically unexplained ("functional") syndromes and the poor relationship between objective and subjective health indicators in general.     

Simplified learning in complex situations: knowledge partitioning in function learning

The authors explored the phenomenon that knowledge is not always integrated and consistent but may be partitioned into independent parcels that may contain mutually contradictory information. In 4 experiments, using a function learning paradigm, a binary context variable was paired with the continuous stimulus variable of a to-be-learned function. In the first 2 experiments, when context predicted the slope of a quadratic function, generalization was context specific. Because context did not predict function values, it is suggested that people use context to gate separate learning of simpler partial functions. The 3rd experiment showed that partitioning also occurs with a decreasing linear function, whereas the 4th study showed that partitioning is absent for a linearly increasing function. The results support the notion that people simplify complex learning tasks by acquiring independent parcels of knowledge.
