Activity Restriction and Depressive Symptoms in Older Couples.

OBJECTIVE: The present study aimed to clarify the circumstances under which activity restriction (AR) is associated with depressive symptoms among patients with osteoarthritis (OA) and their spouses. METHOD: A total of 220 older adults with OA and their caregiving spouses participated in the study. The actor-partner interdependence model (APIM) was used to examine the associations between AR stemming from patients' OA and the depressive symptoms of patients and spouses. The potential moderating role of marital satisfaction also was examined. RESULTS: After accounting for pain severity, health, and life stress of both patients with OA and spouses, higher AR was associated with more depressive symptoms for both patients and spouses. In regard to partner effects, patients whose spouse had higher AR reported more depressive symptoms. In addition, the association of spouses' and patients' AR and their own depressive symptoms was moderated by their marital satisfaction. For both patients and spouses, the associations between their own AR and depressive symptoms were weaker for those with higher levels of marital satisfaction compared with those with lower levels of marital satisfaction. DISCUSSION: This pattern of findings highlights the dyadic implications of AR and the vital role of marital satisfaction in the context of chronic illness.

Effectiveness and cost-effectiveness of an internet intervention for family caregivers of people with dementia: design of a randomized controlled trial.

BACKGROUND: The number of people with dementia is rising rapidly as a consequence of the greying of the world population. There is an urgent need to develop cost effective approaches that meet the needs of people with dementia and their family caregivers. Depression, feelings of burden and caregiver stress are common and serious health problems in these family caregivers. Different kinds of interventions are developed to prevent or reduce the negative psychological consequences of caregiving. The use of internet interventions is still very limited, although they may be a cost effective way to support family caregivers in an earlier stage and diminish their psychological distress in the short and longer run. METHODS/DESIGN: A pragmatic randomized controlled trial is designed to evaluate the effectiveness and cost-effectiveness of 'Mastery over Dementia', an internet intervention for caregivers of people with dementia. The intervention aims at prevention and decrease of psychological distress, in particular depressive symptoms. The experimental condition consists of an internet course with 8 sessions and a booster session over a maximum period of 6 months guided by a psychologist. Caregivers in the comparison condition receive a minimal intervention. In addition to a pre and post measurement, an intermediate measurement will be conducted. In addition, there will be two follow-up measurements 3 and 6 months after post-treatment in the experimental group only. To study the effectiveness of the intervention, depressive symptoms are used as the primary outcome, whereas symptoms of anxiety, role overload and caregiver perceived stress are used as secondary outcomes. To study which caregivers profit most of the internet intervention, several variables that may modify the impact of the intervention are taken into account. Regarding the cost-effectiveness, an economic evaluation will be conducted from a societal perspective. DISCUSSION: This study will provide evidence about the effectiveness and cost-effectiveness of an internet intervention for caregivers. If both can be shown, this might set the stage for the development of a range of internet interventions in the field of caregiving for people with dementia. This is even more important because future generations of caregivers will be more familiar with the use of internet. TRIAL REGISTRATION: NTR-2051/RCT-DDB.
