Sleep and affect in older adults: using multilevel modeling to examine daily associations

The main objective of the present study was to examine daily associations (intraindividual variability or IIV) between sleep and affect in older adults. Greater understanding of these associations is important, because both sleep and affect represent modifiable behaviors that can have a major influence on older adults’ health and well‐being. We collected sleep diaries, actigraphy, and affect data concurrently for 14 days in 103 community‐dwelling older adults. Multilevel modeling was used to assess the sleep–affect relationship at both the group (between‐persons) and individual (within‐person or IIV) levels. We hypothesized that nights characterized by better sleep would be associated with days characterized by higher positive affect and lower negative affect, and that the inverse would be true for poor sleep. Daily associations were found between affect and subjective sleep, only and were in the hypothesized direction. Specifically, nights with greater reported awake time or lower sleep quality ratings were associated with days characterized by less positive affect and more negative affect. Gender was not a significant main effect in the present study, despite previous research suggesting gender differences in the sleep–affect relationship. The fact that self‐ratings of sleep emerged as the best predictors of affect may suggest that perceived sleep is a particularly important predictor. Finally, our results suggest exploration of affect as a potential intervention target in late‐life insomnia is warranted.

The therapeutic alliance in the cognitive behavioral treatment of pediatric obsessive–compulsive disorder ☆

Although cognitive-behavioral therapy (CBT) for pediatric obsessive-compulsive disorder (OCD) is considered a first-line treatment, not all youth have a positive treatment response, suggesting need for investigating factors that may enhance or reduce treatment effects. Few studies have investigated predictors of treatment response in pediatric OCD, and there is an absence of studies examining the influence of treatment process variables (e.g., therapeutic alliance [TA]) on treatment outcome. Using a multiple-informant and multiple-time point design, the current study examined the role of the TA in family-based CBT for pediatric OCD. Analyses examined (1) the predictive value of the TA on OCD symptom reduction and (2) whether changes in the TA over time predict treatment response. Findings indicated that (1) stronger child-rated, parent-rated, and therapist-rated TAs were predictive of better treatment outcome and (2) larger and more positive early alliance shifts (as rated by changes in child-rated TA between sessions 1 and 5) were predictive of better treatment outcome. Implications for the treatment of youth with OCD within family-based CBT are discussed.

Sleep disturbances associated with cigarette smoking

Sleep disturbances resulting in insufficient sleep have been linked to negative physical, cognitive, and public health outcomes. Despite this, there has yet a study that examines the impact of smoking on sleep in a US based national sample. The current study sought to observe sleep disturbances associated with smoking status. Sleep disturbances in adults aged 20 years and above, from the 2005–2006 National Health and Nutrition Examination Survey, were measured among current, former, and never smokers (NS). Current smokers (CS) reported significantly less total sleep time, longer sleep onset latency, increased difficulty falling asleep, maintaining sleep, and waking up earlier than desired when compared to NS. Former smokers reported disturbances similar to NS and CS experienced poorer sleep than nonsmokers. Our study is the first to observe sleep difficulty by smoking status in a large, population-based, nationally representative sample. Recommendations for smoking cessation programs are discussed.

Co-occurring weight problems among children with attention deficit/hyperactivity disorder: the role of executive functioning

OBJECTIVE:To explore the link between pediatric obesity and attention deficit/hyperactivity disorder (ADHD) by examining whether executive functioning (EF) and medication status are associated with body mass index (BMI) and weight status in children with ADHD.METHOD:Participants for this study included 80 children (mean age=10 years, 9 months) with a DSM-IV diagnosis of ADHD, confirmed by a comprehensive clinical diagnostic assessment. Childrens EF was measured using three neuropsychological tests, and severity of ADHD symptoms and medication status were obtained from parent report. Childrens height and weight were also measured during the visit using a wall-mounted stadiometer and a balance beam scale.RESULTS:Children with ADHD who performed poorly on the neuropsychological battery had greater BMI z-scores, and were more likely to be classified as overweight/obese compared with children with ADHD who performed better on the neuropsychological battery. In addition, children with ADHD who were taking a stimulant medication had significantly lower BMI z-scores compared with children with ADHD who were not taking medication or who were taking a non-stimulant medication.CONCLUSION:EF is more impaired among children with ADHD and co-occurring weight problems, highlighting the importance of self-regulation as a link between pediatric obesity and ADHD.

Daily Variations in Objective Nighttime Sleep and Subjective Morning Pain in Older Adults with Insomnia: Evidence of Covariation over Time

OBJECTIVES: To examine the relationship between objectively measured nocturnal sleep and subjective report of morning pain in older adults with insomnia; to examine not only the difference between persons in the association between sleep and pain (mean level over 14 days), but also the within‐person, day‐to‐day association.

ADHD symptomatology and risky health, driving, and financial behaviors in college: the mediating role of sensation seeking and effortful control

Objective: To examine the extent to which effortful control (EC) and sensation seeking (SS) tendencies explain the association between the severity of ADHD symptoms and risky behaviors. Method: Participants included 555 college students (66% females) who completed self-report measures assessing their ADHD symptoms, EC abilities, SS tendencies, and risky health (e.g., substance use) and driving/financial behaviors (e.g., misuse of credit cards). Results: Severity of college students’ ADHD symptoms, EC abilities, and SS tendencies were related to all risky behaviors. Multiple mediational analyses further indicated that students’ SS tendencies significantly mediated the association between ADHD symptoms and the risky health factor but not the risky driving/financial factor. EC, however, significantly mediated the association between ADHD symptoms and both the risky health and driving/financial factors. Conclusion: The current study provides initial data showing potentially different mechanisms that explain the link between college students’ severity of ADHD symptoms and risky behaviors.

Differentiating co-occurring behavior problems in children with ADHD: patterns of emotional reactivity and executive functioning.

Objective: This study examined whether “top-down” and “bottom-up” control processes can differentiate children with ADHD who exhibit co-occurring aggression and/or internalizing symptoms. Method: Participants included 74 children (M age = 10.7 years) with a Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) diagnosis of ADHD. The authors’ top-down measure was executive functioning (EF) indexed via two neuropsychological tasks whereas their bottom-up measure was emotional reactivity. Parents also reported on children’s aggression and internalizing symptoms. Results: Emotional reactivity was associated with co-occurring aggressive symptoms, regardless of the presence of internalizing symptoms or ADHD symptom severity, whereas EF deficits were less likely to occur in children with ADHD and co-occurring internalizing symptoms. Conclusion: The authors’ findings highlight the importance of integrating top-down and bottom-up regulatory measures when studying the multipathway conception of ADHD and its co-occurring problems.

The diabetes online community: the importance of forum use in parents of children with type 1 diabetes

Online forums for chronic health conditions emerged as early as 30 yr ago and interest in their study has blossomed. Type 1 diabetes (T1D) forums have grown exponentially since 2005. Therefore, a comprehensive evaluation of these forums is needed. This study assesses the demographics and motivations of parents who use type 1 diabetes forums and the potential impact that forum membership (FM) has on parenting stress and hypoglycemic fear. One hundred and two parents were recruited through online T1D forums and asked to complete qualitative and quantitative measures of their experience with the T1D forums. Results of this study suggest that parents who use T1D forums mirror those who participate in clinic‐based research protocols and are primarily motivated to participate in forums to increase their diabetes knowledge and gain social support. Indeed, parents who use T1D forums report high levels of trust, social support, and perceived knowledge gained. However, FM was positively related to increased self‐reported parenting stress frequency and hypoglycemic fear behaviors. Taken together, the relationships formed within these communities may have a significant impact on the experience of these caregivers. The need for future research and potential implications for physicians, including parent debriefing, are discussed.

Psychometric properties of the Treatment-Emergent Activation and Suicidality Assessment Profile (TEASAP) in youth with OCD

This study evaluated the psychometric properties of the treatment-emergent activation and suicidality assessment profile (TEASAP) in a clinical sample of 56 youth aged 7-17 with obsessive-compulsive disorder (OCD) who participated in a double-blind randomized controlled trial. The 38-item TEASAP demonstrated good internal consistency for its total score (α=0.93) and adequate to good performance for its five subscale scores (α=0.65-0.92). One-week test-retest stability (N=18) was adequate (Intraclass correlation coefficient [ICC]=0.68-0.80) except for Self-Injury (ICC=0.46). Construct validity was supported by total and subscale TEASAP score relationships with related constructs, including irritability, hyperactivity, externalizing behaviors, manic symptoms, and suicidal ideation, and the absence of relationships with unrelated constructs. Predictive validity was established for the Disinhibition subscale through significant associations with subsequent activation events. Furthermore, TEASAP sensitivity to change in activation scores over time was supported by longitudinal associations of TEASAP scores with clinician ratings of activation over the course of treatment. Findings indicate that the TEASAP has acceptable psychometric properties in a clinical sample of youth with OCD and merits further study in larger samples for additional refinement of its measurement approaches.

Associations between miscellaneous symptoms and symptom dimensions in adults with obsessive-compulsive disorder

Abstract Obsessive-compulsive disorder (OCD) is a debilitating psychiatric condition with a heterogeneous array of obsessions and compulsions. Although factor analytic studies have identified symptom dimensions comprising the clinical presentation of OCD, many frequently reported miscellaneous symptoms are not considered in factor analytic studies because they do not fit conceptually within a particular symptom category, despite being functionally related. In the present study, we examined the associations between miscellaneous symptoms and OCD symptom dimensions in a sample of 111 adults with OCD. Overall, most miscellaneous symptoms were associated with one or more symptom dimensions in previously identified four- (14 of the 22 symptoms) and five-factor models (12 of the 22 symptoms). In both models, Contamination/Cleaning was the only dimension not related to any miscellaneous symptom. The present results provide information about which miscellaneous symptoms may be related to particular symptom dimensions, which will assist in clinical evaluations and help planning behavioral psychotherapy (e.g., hierarchy development).
