• Lead Sponsor: University of California, San Francisco

Brief Summary

Life Enhancing Activities for Family Caregivers is a six-week program designed to increase positive affect in people who care for a family member with dementia. The intervention consists of 6 weekly one-hour sessions conducted one-on-one with a trained facilitator to teach simple skills that are practiced at home in a study-supplied workbook. The program is preceded and followed by a 30-45 minute questionnaire. Follow-up assessments will be conducted at 1-month, 3-months, and 6-months post intervention.

Primary hypothesis is that experimental subjects who participate in LEAF will demonstrate significantly greater improvements in psychological outcomes and will engage in more problem focused and positive appraisal forms of coping compared to the wait-list control condition.

Detailed Description

All study activities can be conducted from the participant's home, making participation possible for any qualified caregiver with computer and wifi access, in any U.S. state. The LEAF study will supply the tablet computer, software, and workbook required for participation.

Primary Outcome Measures

Name	Time	Method
Repeated measures of the modified version of the Differential Emotions Scale (DES) (Izard, 1977)	Baseline and weeks 6 and 10; 3-months and 6-months post	The DES will be used to assess positive and negative affect. This 20-item version of the DES was modified to include additional positive affect items as well as those that are likely to tap into trait positive affectivity. The full scale assesses interest, enjoyment, surprise, sadness, anger, disgust, contempt, fear, guilt, shame, shyness, amusement, awe, contentment, gratitude, hope, love, pride, sympathy, and sexual feelings (e.g., "I felt sexual, desiring, and flirtatious"). The scale can be scored for total positive and negative affect,grouped according to where they would fall on the circumplex model of affect (e.g., high activation vs. lower activation),or individual affects can be examined. In student samples this modified DES has shown acceptable reliability with the positive affects subscale (α = .79) and the negative affects subscale (α = .69).

Secondary Outcome Measures

Name	Time	Method
Change in perceived stress at end of intervention, 3 and 6-months post - Perceived Stress Scale (PSS) (Cohen, 1988)	Baseline and weeks 6 and 10; 3-months and 6-months post	The 10 items are designed to identify how unpredictable, uncontrollable and overloaded respondents find their lives. Scores range from 0-40, with higher scores indicating greater stress.
Change in coping at end of intervention, 3 and 6-months post - Ways of Coping Scale (Folkman, Lazarus, Pimley, & Novacek, 1987)	Baseline and weeks 6 and 10; 3-months and 6-months post	The 23 forms of coping responses assessed include: confrontive coping, escape-avoidance, planful problem-solving, positive reappraisal, benefit, growth, mastery of stress, other success, purpose, positive relations with others, religion, and respite, benevolent and negative religious coping, emotional processing and expression, goal replacement, and maintaining optimism.
Change in anxiety at end of intervention, 3 and 6-months post - Emotional Distress - Anxiety, PROMIS Item Bank v. 1.0 (Cella et al., 2010)	Baseline and weeks 6 and 10; 3-months and 6-months post	Used to assess anxiety.
Change in burden at end of intervention, 3 and 6-months post - Zarit Burden Inventory (Zarit, Reever, & Bach-Peterson, 1980)	Baseline and weeks 6 and 10; 3-months and 6-months post	22-item inventory assesses caregivers' subjective feelings of the impact of caregiving on emotional and physical health functioning, social life, and financial status.
Change in depression at end of intervention, 3 and 6-months post - Depression, Patient Reported Outcomes Measurement Information System Item Bank, v. 1.0 (PROMIS; Cella et al., 2010)	Baseline and weeks 6 and 10; 3-months and 6-months post	Used to assess depressive mood.
Change in caregiver strain at end of intervention, 3 and 6-months post - Caregiver Strain Index (CSI) (Robinson, 1983)	Baseline and weeks 6 and 10; 3-months and 6-months post	The CSI is a 13-item measure of both objective and subjective elements of caregiver strain.
