Assessing the Impact of Weighted Blankets on Anxiety Among Patients With Anorexia Nervosa and Avoidant- Restrictive Food Intake Disorder: A Randomized Controlled Trial.

IMPORTANCE: Interventions to reduce anxiety are needed for patients with anorexia nervosa (AN) and avoidant- restrictive food intake disorder (ARFID). Weighted blankets are one such intervention. OBJECTIVE: To evaluate the impact of weighted blankets on anxiety for patients with AN and ARFID. DESIGN: Randomized controlled trial conducted between November 2018 and March 2019. Patients were randomized into the control group or the intervention group. SETTING: Inpatient setting; medical stabilization unit. PARTICIPANTS: Patients (N = 23) diagnosed with AN or ARFID and experiencing moderate anxiety. The majority were female (91%), with a mean age of 26 yr (SD = 9.3), and the mean length of hospitalization was 22 days (SD = 17.3). INTERVENTIONS: Control group participants received usual care, which included occupational therapy services. Intervention group participants received a weighted blanket along with usual care. OUTCOMES AND MEASURES: Mixed-effects regression models were conducted. Primary outcomes included improvement in Beck Anxiety Inventory (BAI) scores by discharge. RESULTS: Intervention group patients had a greater, non-statistically significant decrease in BAI score over time (B = 1.16, p = .83) than control group patients. CONCLUSIONS AND RELEVANCE: Weighted blankets may be an effective tool for reducing anxiety among patients with AN or ARFID. What This Article Adds: The use of a weighted blanket, in conjunction with occupational therapy interventions, is potentially a beneficial non-pharmacological option for patients with anorexia nervosa (AN) and avoidant-restrictive food intake disorder (ARFID). The current study adds an additional modality to the multidisciplinary treatment approach for eating disorders.

Cognitive bias modification for threat interpretations: Impact on anxiety symptoms and stress reactivity.

BACKGROUND: Cognitive bias modification for interpretations (CBM-I) is a computerized intervention that has received increasing attention in the last decade as a potential experimental intervention for anxiety. Initial CBM-I trials with clinical populations suggest the potential utility of this approach. However, most CBM-I experiments have been conducted with unaffected samples, few (one or two) training sessions, and have not examined transfer effects to anxiety-related constructs such as stress reactivity. METHOD: This study compared a 12-session CBM-I intervention (n = 12) to an interpretation control condition (ICC; n = 12) in individuals (N = 24) with elevated trait anxiety on interpretation bias, anxiety symptom, and stress reactivity outcomes (electrodermal activity, heart rate, and respiratory sinus arrhythmia). RESULTS: Compared to the ICC group, participants assigned to CBM-I experienced significantly greater improvements in interpretation bias and anxiety symptoms by post-intervention 4 weeks later, with impact on anxiety maintained at 1-month follow-up. While CBM-I and ICC groups did not differ in stress reactivity during an acute stressor at pre-intervention, the CBM-I group evidenced improved stress reactivity at post-intervention compared to ICC on two psychophysiological indices, electrodermal activity and heart rate. CONCLUSIONS: The results of this pilot study suggest that CBM-I may hold promise for reducing anxiety symptoms, as well as impact psychophysiological arousal during an acute stressor.

Weighted Blanket Use: A Systematic Review.

IMPORTANCE: Sensory integration modalities, such as weighted blankets, are used in occupational therapy practice to assist with emotional and physical regulation. However, the research related to the use and effectiveness of weighted blankets is sparse. OBJECTIVE: To identify, evaluate, and synthesize the current literature to help develop the impetus needed to launch a research study into the effectiveness of using weighted blankets to decrease anxiety and insomnia. DATA SOURCES: A literature search was conducted between January 23, 2018, and March 1, 2018. Databases and sites included the Cochrane Library, PubMed, PsycINFO, CINAHL, OTseeker, Web of Science, and Nursing Reference Center Plus. Search terms included weighted blanket, deep pressure, and occupational therapy as well as combinations of these terms. STUDY SELECTION AND DATA COLLECTION: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles were included if the study used weighted blankets as the modality of deep pressure stimulation. Data from presentations, conference proceedings, non-peer-reviewed literature, dissertations, and theses were excluded. FINDINGS: Only 8 studies were included: 4 Level I, 2 Level III, and 2 Level IV studies. The outcomes of these studies suggest that weighted blankets have the potential to be beneficial in limited settings and populations. CONCLUSION AND RELEVANCE: Weighted blankets may be an appropriate therapeutic tool in reducing anxiety; however, there is not enough evidence to suggest they are helpful with insomnia. WHAT THIS ARTICLE ADDS: Evidence-based research on the effectiveness of weighted blankets in reducing anxiety and insomnia is sparse. More research is needed to define guidelines for the use of weighted blankets in clinical practice and to investigate the underlying mechanism of action. This systematic review can be used to begin an investigation of the use of weighted blankets for larger and more diverse populations.

The Lived Environment Life Quality Model for institutionalized people with dementia.

BACKGROUND: There is a need for a conceptual practice model that explicates ecological complexities involved in using occupation to optimize the quality of life of institutionalized people with dementia. PURPOSE: This study aimed to prepare the Lived Environment Life Quality Model, a dementia-specific conceptual practice model of occupational therapy in institutional facilities, for publication and application to practice. METHOD: Interviews and focus groups with six expert occupational therapists were subjected to qualitative content analysis to confirm, disconfirm, and further develop the model. FINDINGS: The model's lived-environment domain as the focus of assessment and intervention was extensively confirmed, and its quality-of-life domain as the focus of intervention goals and outcomes was both confirmed and further developed. IMPLICATIONS: As confirmed in this study, the Lived Environment Life Quality Model is a client-centred, ecologically valid, and occupation-focused guide to optimizing quality of life of institutionalized adults with dementia in present moments and progressively over time.
