Impulse control disorders in Parkinson’s disease: Predominant role of psychological determinants

Objectives: Impulse Control Disorders (ICDs) in Parkinson’s disease (PD) have previously almost exclusively been considered to result from anti-parkinsonian medication. However, this biomedical perspective has failed to achieve a full understanding of the phenomenon and it is argued that a failure to consider psychological factors is a critical omission.

Design: The present study examined the predictive relationship between ICDs in PD and a range of psychological measures, whilst controlling for a number of biomedical determinants.

Main outcome measures: One hundred participants with idiopathic PD completed questionnaires that assessed demographic and clinical characteristics, psychological measures and the presence of ICDs (QUIP-RS).

Results: Increased use of a ‘negative’ coping strategy, stronger illness identity, more emotional illness representations and stress were found to be significant predictors of ICDs, and different psychological predictors were associated with different ICDs. Medication was not found to predict ICDs in the presence of psychological factors, either when total treatment levels were considered or when agonist dose was considered alone.

Conclusions: This study provides the first quantitative evidence of a predominant predictive relationship between psychological factors and ICDs in PD. The results suggest that psychological interventions may have useful therapeutic role to play for ICDs in PD.     

Early Developmental Screening for Children in Foster Care

Limited data exist about the ideal timing of developmental screening for young children entering foster care, and current best practice recommends screening by 1 month into care to prioritize resources for evaluation. Therefore, we aimed to: (1) compare detection rates for potential developmental delay (DD) at foster care entry before and after implementation of a developmental screen and (2) examine accuracy of developmental screening when performed at entry and 1 month into care. Charts of 124 children <6 years evaluated for an initial foster care health assessment (IFCHA) were reviewed to determine baseline detection rates for potential DD. The Parents’ Evaluation of Developmental Status (PEDS) screening tool was then prospectively administered to 167 children <6 years during their IFCHA to determine detection rates. One month following the IFCHA, caregivers were re-contacted, and the screen was re-administered. Accuracy of the initial PEDS screen was compared to the 1 month PEDS screen by calculation of sensitivity and specificity. At baseline, potential DD was detected in 34 % of children at the IFCHA compared to 46 % after implementation of the PEDS (P = 0.041). Compared to the 1 month screen, the early screen had a sensitivity of 75 % and specificity of 88 %. Use of a developmental screening tool at foster care entry increased detection of potential DD, and the results remained consistent with screening 1 month later. These results support use of a developmental screen for children in foster care and suggest that screening be performed as early as possible to expedite necessary evaluations and referrals.     

Frequency and impact of trauma in older women: A military and nonmilitary sample

Understanding the impact of trauma on late-life functioning in older females is needed in order to provide best care. We explored the impact of trauma on late-life psychological and physical health and functioning among older women (n = 48) who served in the military, or participated in a military lifestyle. Eleven of these women were not veterans, but married to military personnel. Number of traumatic exposures and types of events experienced was associated with increased trauma symptom severity. Trauma symptom severity was associated with decreased physical functioning and increased pain. Increased numbing and avoidance was significantly associated with poorer physical functioning and increased pain. Older women in this study remained at risk of experiencing negative consequences of trauma in terms of increased quantity and severity of trauma symptoms and physical decline and pain. Clinical and research implications are discussed.     

Predicting Treatment Outcomes From Internet-Based Cognitive Behavior Therapy for Obsessive–Compulsive Disorder

Internet-based cognitive-behavioral therapy (ICBT) with therapist support shows promise as a treatment for obsessive-compulsive disorder (OCD). Yet, not all patients respond to ICBT. It is therefore important to identify predictors of ICBT outcomes to determine who is likely to benefit. Relative to the large literature on predictors of outcomes for in-person CBT for OCD, very few studies have investigated ICBT predictors. Therefore, we analyzed predictors of outcome in an open trial (n = 30) of ICBT for OCD using the OCD-NET platform, which consists of 10 online modules delivered with therapist support. The Yale-Brown Obsessive-Compulsive Scale (YBOCS) was administered by independent raters as the primary outcome measure at baseline and posttreatment. In this sample, greater baseline OCD severity and OCD-related avoidance behaviors were associated with higher end-state OCD symptoms (i.e., poorer outcome). Patients with a past history of face-to-face CBT for OCD also had worse outcomes. Although these results require replication, these factors may identify individuals at risk for poor ICBT outcomes.     

Evaluating the predictive validity of the computerized comprehension task: comprehension predicts production

Until recently, the challenges inherent in measuring comprehension have impeded our ability to predict the course of language acquisition. The present research reports on a longitudinal assessment of the convergent and predictive validity of the MacArthur-Bates Communicative Development Inventories: Words and Gestures (CDI: WG; Fenson et al., 1994, 1993, 2007) and the Computerized Comprehension Task (CCT; Friend & Keplinger, 2003, 2008). The CDI: WG and the CCT evinced good convergent validity; however, the CCT better predicted subsequent parent reports of language production. Language sample data in the 3rd year confirm this finding: The CCT accounted for 24% of the variance in unique word use. These studies provide evidence for the utility of a behavior-based approach to predicting the course of language acquisition into production.     

Couple therapy for military veterans: overall effectiveness and predictors of response

Despite the numerous challenges facing U.S. veterans and their relationships, there have been no examinations of the effectiveness of couple therapy for relationship distress provided to veterans. In the present study, 177 couples presenting for couple therapy at two Veteran Administration Medical Centers completed assessments of relationship satisfaction prior to therapy and weekly during therapy. Results revealed that the average couple showed significant gains in relationship satisfaction during treatment (d=0.44 for men; d=0.47 for women); gains were larger for couples beginning therapy in the distressed range (d=0.61 for men; d=0.58 for women) than for couples in the nondistressed range (d=0.19 for men; d=0.22 for women). Rates of premature termination were high, with 19% of couples completing fewer than three sessions and 62% rated as not completing a "full course" of therapy. Benchmarking analyses demonstrated that the average gains were larger than would be expected from natural remission and similar to previous effectiveness trials; however, average gains were smaller than those observed in couple therapy efficacy trials. Relationship, psychological, and demographic characteristics were generally unrelated to the amount of change in therapy after controlling for initial satisfaction. However, African American couples showed significantly larger gains than Caucasian, non-Hispanic couples. Thus, though yielding smaller effects than those shown in efficacy trials, the impact of couple therapy for veterans' relationship problems appears to generalize across various demographic, psychological, and relationship characteristics.     

Ovulation leads women to perceive sexy cads as good dads

Why do some women pursue relationships with men who are attractive, dominant, and charming but who do not want to be in relationships--the prototypical sexy cad? Previous research shows that women have an increased desire for such men when they are ovulating, but it is unclear why ovulating women would think it is wise to pursue men who may be unfaithful and could desert them. Using both college-age and community-based samples, in 3 studies we show that ovulating women perceive charismatic and physically attractive men, but not reliable and nice men, as more committed partners and more devoted future fathers. Ovulating women perceive that sexy cads would be good fathers to their own children but not to the children of other women. This ovulatory-induced perceptual shift is driven by women who experienced early onset of puberty. Taken together, the current research identifies a novel proximate reason why ovulating women pursue relationships with sexy cads, complementing existing research that identifies the ultimate, evolutionary reasons for this behavior.     

Bringing relationships into consumer decision‐making

The primary purpose of our target article was to stimulate further interest in and research on consumer decision-making in close relationships. In this response, we discuss some of the major comments provided by each set of commentators by highlighting their main points, clarifying some misconceptions, and explaining why our dyadic framework is a logical starting-point for research on how relationships affect consumer decisions.
