Acculturation and mental health: Current findings and recommendations for future research

Results of existing literature suggest that the relationship between acculturation and mental health is complex. Some studies have found a beneficial association between increased acculturation and mental health, whereas others have found a detrimental association or no relationship at all. We reviewed literature on acculturation and mental health in Hispanics/Latino Americans, Asians/Asian Americans, and other ethnic groups. Results indicate that greater acculturation is associated with increased substance use and abuse. Findings for other disorders and symptoms demonstrate considerable heterogeneity and potential reasons for this variation are provided. Acculturation involves a complex set of processes that appear to have differential impact on mental health outcomes. Critical issues in the measurement of acculturation are discussed, and recommendations for future research are offered.     

Mothering under political violence: Post-traumatic symptoms,observed maternal parenting practices and child externalising behaviour

Using the family stress model as our conceptual framework, we explored whether observed maternal parenting practices (positive and coercive) account for the associations between mothers' post-traumatic stress symptoms and children's externalising behaviours. Mothers' self-reported post-traumatic stress symptoms, observed maternal practices, and reports of children's externalising behaviour were collected from 123 Israeli mothers and their children, who were exposed to ongoing rocket attacks in southern Israel. A structural equation model revealed that mothers' post-traumatic stress symptoms were linked with greater maternal coercive parenting practices, which in turn were associated with more externalising behaviours in children. The study highlights the crucial role of maternal distress and mothers' parenting skills in the development of externalising behaviours in children exposed to chronic political violence. These results suggest that prevention interventions designed to promote parenting skills for mothers exposed to political violence may be beneficial for children's healthy development.     

Testing a Military Family Stress Model

The current study examines a military family stress model, evaluating associations between deployment‐related stressors (i.e., deployment length/number, posttraumatic stress disorder [PTSD] symptoms) and parent, child, parenting, and dyadic adjustment among families in which a parent had previously deployed to Iraq or Afghanistan in the recent conflicts. Married families (N = 293) with at least one child between the ages of 4 and 12 were recruited from a Midwestern state. Service members were from the Reserve Component (National Guard or Reserves); fathers (N = 253) and/or mothers had deployed (N = 45) to the recent conflicts in the Middle East. Multiple‐method (observations of parenting and couple interactions; questionnaires) and multiple informant measures were gathered online and in the homes of participants, from parents, children, and teachers. Findings demonstrated associations between mothers’ and fathers’ PTSD symptoms and a latent variable of child adjustment comprising teacher, parent, and child report. Mothers’ but not fathers’ PTSD symptoms were also associated with dyadic adjustment and parenting practices; parenting practices were in turn associated with child adjustment. The results are discussed in terms of their implications for military family stress research and interventions to support and strengthen parents and families after deployment.     

Assessment of Interpersonal Influences on Adolescents: The Parent and Peer Influence Scale

Peer influence is a common topic of interest for parents, clinicians, and researchers, but results from research on the relative importance of parents’ versus peers’ influence on adolescents and young adults has been contradictory. For example, some research suggests that peer attitudes about school influences future academic aspirations, other research suggests that parents and peers differ on their level of influence based on topic (e.g., parents’ are the primary source of influence about moral issues), and other research suggests that peer-oriented children are a product of parental disregard. A reliable and valid measure of the relative strength of parent versus peer influence could enhance research in this area. As a result, the Parent and Peer Inventory Scale (PPI) was developed, which demonstrates strong reliability as well as face and concurrent validity. The PPI can be used both by researchers to address contradictions in the literature, as well as clinicians seeking to evaluate level of peer influence in a family.     

Emotions as signals of normative conduct

Social interactions are heavily norm-based and these norms need to be learned. For this, the emotional reactions of other's in response to a norm transgression can serve as signals. We were able to show that when a group responds with anger to a norm transgressing behaviour, participants were better able to correctly infer the norm than when the group responded with sadness or emotional neutrality. We further tested a process-model showing that this inference is based on the participants' understanding of the groups' appraisals of the behaviour. That is, participants who were able to reverse engineer the underlying appraisal of norm-incompatibility from the emotion expressions inferred the norm more readily. Humans as a social species, require efficient means to quickly adapt to new situations and to perform flawlessly in social contexts. Emotion information is one of the instruments that can be used in this quest.     

Social rank and affiliation in social anxiety disorder

The present study examined the interpersonal lives of individuals with social anxiety disorder (SAD). According to evolutionary and interpersonal theories, we construed the interpersonal world using the social rank and the affiliation psychological systems. Two studies assessed measures of social rank, affiliation, social anxiety and depression among a population of treatment-seeking individuals with SAD. In study 1, individuals with SAD without major depressive disorder (MDD; n=42) were compared to healthy controls (n=47). In study 2, individuals with SAD and MDD (n=45) were compared to individuals with other anxiety disorders and MDD (n=31). Results indicated that SAD was related to perceiving oneself as having low social rank, being inferior, and behaving submissively, as well as to low perceived intimacy and closeness among peer relations, friendships and romantic relations. SAD was distinctly associated with these perceptions above and beyond the symptomatic (study 1) and the syndrome-level (study 2) effects of depression. These findings were further supported by a path analysis of the SAD participants from both studies. Our findings highlight the need to address both social rank and affiliation issues in the assessment and treatment of SAD.     

Response-dependent shock in second-order fixed-ratio schedules of food presentation

Three pigeons key pecked under second-order schedules in which the completion of two successive fixed-ratio 50 components constituted a reinforcement cycle. Tandem, chained, and brief-stimulus second-order schedules were studied when completion of the initial fixed-ratio 50 component delivered brief intense electric shock in every nth reinforcement cycle and n assumed values between one and nine. During sessions without shock, the brief-stimulus (unpaired with food) schedule generated higher rates of responding in the initial component than did the tandem schedule. Electric shock engendered increased time to the fifth response and a repeated pause-run pattern of not responding and responding, particuuarly in the initial component, even with shock scheduled in every ninth reinforcement cycle. The results were consistent with those reported for shock of a shorter duration scheduled in every reinforcement cycle. The overall rate of responding decreased as a function of increasing shock density and was lower in brief-stimulus than in tandem schedules.     

A motor-driven feeder for operant training in song birds

Conventional pigeon feeders can make noise, spill food, and injure birds in applications using small song birds as subjects. We developed a motor-driven feeder based on the principle of the piston to address these concerns.
