Factor structure of the Penn State Worry Questionnaire: examination of a method factor

The Penn State Worry Questionnaire (PSWQ) was originally designed as a unifactorial measure of pathological trait worry. However, recent studies supported a two-factor solution with positively worded items loading on the first factor and reverse-scored items loading on a second factor. The current study compared this two-factor model to a negative wording method factor solution among college students. A method factor model with all PSWQ items loading on a single worry factor and reverse-scored items loading on a negative wording method factor provided as good a fit as the two-factor model. This method factor alone did not predict a generalized anxiety disorder diagnosis. Finally, the psychometric properties of an abbreviated scale containing only positively worded items were examined. The PSWQ appears to measure a single unitary construct, but response patterns differ between positively worded and reverse-scored items. Theoretical implications for pathological worry and assessment-related issues are discussed.     

Women's Reactions to Rape Victims: Motivational Processes Associated With Blame and Social Support1

A study was conducted with 128 female college students to test the hypothesis that when observers feel vulnerable to rape, they are more likely to blame a rape victim³ and are less willing to offer social support. Similarity and empathy were expected to moderate the effects of perceived vulnerability on blame and predict greater social support. Assumptions about the world were predicted to be associated with greater blame. A multivariate model was tested with structural equation modeling techniques. Perceived vulnerability did not directly or indirectly predict blame. However, similarity directly predicted less blame and indirectly predicted greater social support through associations with blame, perceived vulnerability, and empathy. World assumptions directly predicted greater blame and indirectly predicted less social support through blame. These findings suggest that blame and social support are interrelated processes which are associated with social observers' perceptions of the victim and their basic assumptions about the world.     

Structural equation modeling: reviewing the basics and moving forward

This tutorial begins with an overview of structural equation modeling (SEM) that includes the purpose and goals of the statistical analysis as well as terminology unique to this technique. I will focus on confirmatory factor analysis (CFA), a special type of SEM. After a general introduction, CFA is differentiated from exploratory factor analysis (EFA), and the advantages of CFA techniques are discussed. Following a brief overview, the process of modeling will be discussed and illustrated with an example using data from a HIV risk behavior evaluation of homeless adults (Stein & Nyamathi, 2000). Techniques for analysis of nonnormally distributed data as well as strategies for model modification are shown. The empirical example examines the structure of drug and alcohol use problem scales. Although these scales are not specific personality constructs, the concepts illustrated in this article directly correspond to those found when analyzing personality scales and inventories. Computer program syntax and output for the empirical example from a popular SEM program (EQS 6.1; Bentler, 2001) are included.     

Training Young Adult Peers in a Mobile Motivational Interviewing‐Based Mentoring Approach to Upstream HIV Prevention

Mentoring relationships are characterized by a sustained, high quality, and skill‐building relationship between a protégé and mentor (Handbook of Youth Mentoring, Los Angeles, SAGE, 2014). Within prevention science, youth mentoring programs emphasize creating a specific context that benefits a young person. Program‐sponsored relationships between youth and adults allow for creating a mentor–mentee partnership, but do not require the establishment of a strong bond in order to deliver prevention‐focused activities and experiences (Handbook of Youth Mentoring, Los Angeles, SAGE, 2014). Motivational Interviewing (MI) is a counseling style used widely to promote health behavior change and in prevention interventions. As part of an upstream approach to HIV prevention, we combined mentoring and MI by training peer mentors to use MI skills in their interactions as part of a large RCT of a mobile life skills intervention for adolescent men who have sex with men (AMSM). Our training model developed for training peer mentors in MI skills resulted in peers reaching and exceeding established MI fidelity thresholds (e.g., mean percentage of complex reflections = 80%, mean reflection to question ratio = 2.2:1). We offer reflections on lessons learned and future directions for those researchers and practitioners who may benefit from adapting this blended approach for mentoring AMSM.     

Psychological interventions for carers of people with dementia: A systematic review of quantitative and qualitative evidence

Rationale: Carers of people with dementia experience significant levels of stress in their everyday role. The National Dementia Strategy in England identifies the key role that carers play in supporting people with dementia living at home, often to the detriment of their social, emotional and physical health. Aims: To add to the substantive knowledge‐base by combining search criteria used by Pinquart and Sörensen (2006) and Gallagher‐Thompson and Coon (2007) to update the literature on psychological interventions for carers of people with dementia published between 2005 and 2011. Method: Following the study inclusion criteria, comprehensive searches were conducted using the electronic databases Medline, PsycINFO, ERIC, and PubMed. Twenty studies were identified, graded and synthesised into the reported systematic review with both quantitative and qualitative studies included to maximise practice application. Results: Consistent with previous findings, three categories of psychological intervention were identified: (i) psychoeducational‐skill building (n=8); (ii) psychotherapy‐counselling (n=1); (iii) multicomponent (n=6). Our review also identified a fourth intervention category, (iv) technology‐based (n=5). The majority of studies in the updated review examine the constructs of depression, burden, social support and well‐being. The development of focused interventions for carers, whether individually tailored interventions or group interventions around a common issue, was significant for developing practice. Future studies across all categories should continue to embed supervision arrangements within their psychological intervention protocols.     

Changes in children’s perception-action tuning over short time scales: Bicycling across traffic-filled intersections in a virtual environment

This investigation examined short-term changes in child and adult cyclists’ gap decisions and movement timing in response to general and specific road-crossing experiences. Children (10- and 12-year-olds) and adults rode a bicycle through a virtual environment with 12 intersections. Participants faced continuous cross traffic and waited for gaps they judged were adequate for crossing. In the control condition, participants encountered randomly ordered gaps ranging from 1.5 to 5.0 s at all intersections. In the high-density condition, participants encountered high-density intersections sandwiched between sets of control intersections. These high-density intersections were designed to push participants toward taking tighter gaps. Participants in both conditions were more likely to accept 3.5-, 4.0-, 4.5-, and 5.0-s gaps at the last set of intersections than at the first set of intersections, whereas participants in the high-density condition were also more likely to accept very tight 3.0-s gaps at the last intersections than at the first intersections. Moreover, individuals in the high-density condition who waited less and took shorter gaps at the middle intersections were also more likely to take very tight 3.0-s gaps at the last intersections. The 10-year-olds in both conditions had more time to spare when they cleared the path of the oncoming car at the last intersections, whereas the 12-year-olds and adults showed no change in time to spare across intersections. The discussion focuses on linking short-term change in perceptual-motor functioning to longer term perceptual-motor development.     

Combating Co‐witness contamination: Attempting to decrease the negative effects of discussion on eyewitness memory

Witnesses who discuss an event with others often incorporate misinformation encountered during the discussion into their memory of the event. Two experiments were conducted to establish whether this memory conformity also occurs in the context of an interview and whether it is possible to reduce the effect. Participants viewed a crime‐video which they then discussed with a co‐witness. Some participants were warned they may have been exposed to misinformation during the discussion before all were interviewed individually. In Experiment 1, participants made remember/know judgments about each component of their free recall, and in Experiment 2 they were asked to indicate the source of their memories. Co‐witness information was incorporated into participants' testimony, and this effect could not be significantly reduced using warnings and source‐monitoring instructions. Remember/know judgments may be useful in distinguishing ‘real’ memories from false memories. We make some recommendations regarding the interviewing of witnesses.

Synchronizing self and object movement: how child and adult cyclists intercept moving gaps in a virtual environment

Two experiments examined how 10- and 12-year-old children and adults intercept moving gaps while bicycling in an immersive virtual environment. Participants rode an actual bicycle along a virtual roadway. At 12 test intersections, participants attempted to pass through a gap between 2 moving, car-sized blocks without stopping. The blocks were timed such that it was sometimes necessary for participants to adjust their speed in order to pass through the gap. We manipulated available visual information by presenting the target blocks in isolation in Experiment 1 and in streams of blocks in Experiment 2. In both experiments, adults had more time to spare than did children. Both groups had more time to spare when they were required to slow down than when they were required to speed up. Participants' behavior revealed a multistage interception strategy that cannot be explained by the use of a monotonic control law such as the constant bearing angle strategy. The General Discussion section focuses on possible sources of changes in perception-action coupling over development and on task-specific constraints that could underlie the observed interception strategy.     

Pain anxiety, acceptance, and outcomes among individuals with HIV and chronic pain: a preliminary investigation

The current study investigated the role of during treatment changes in pain anxiety in the relation between during treatment changes in pain acceptance and chronic pain outcomes. Participants included 45 (15 women) adults (M_age = 50.42, SD = 7.69) who were HIV positive and experienced chronic pain. They were offered 12 weekly, 90-min group CBT sessions to increase understanding about chronic pain and to improve coping skills. Four hierarchical regression analyses were conducted to examine the mediating role of treatment changes in pain anxiety in the relation between treatment changes in pain acceptance and chronic pain outcomes. Results suggest that increases in pain acceptance during treatment were associated with decreased levels of pain anxiety during treatment, as well as decreases in pain-related impairment at treatment completion. Furthermore, decreases in pain anxiety during treatment were associated with decreases in pain-related impairment at treatment completion. Finally, treatment changes in pain anxiety were found to partially mediate the association between treatment changes in pain acceptance and pain-related impairment at treatment completion. Results are discussed within the context of better understanding the processes of change within a CBT model for chronic pain patients.     

Mother-child communication about location: giving and following directions for finding hidden objects

We conducted 2 experiments to examine how mothers structure directions to young children for finding hidden objects and how young children use these directions to guide their searches. In Experiment 1, we examined the reference frames mothers use to communicate with their 2.5-, 3-, and 3.5-year-old children about location by asking mothers to verbally disambiguate a target hiding container from an identical nontarget hiding container. We found that mothers' reference frame use was primarily governed by the relative proximity of the target container to the landmark and themselves. Older children were more successful in following directions than were younger children, and children were more likely to search successfully in response to a person than to a landmark frame of reference. In Experiment 2, we further investigated how 3-year-old children follow directions involving person and landmark frames of reference by asking mothers to use either only themselves or only the landmark to describe the target location. Children in the person reference frame condition successfully followed their mother's directions when the target was relatively close to the mother, but not when the target was relatively far from the mother. Children in the landmark reference frame condition were at chance regardless of the relative proximity of the target to the landmark. The discussion focuses on the roles of spatial proximity and reference frames in mother-child spatial communication.
