RESUMO
BACKGROUND AND OBJECTIVES: Gate control theory and fear-avoidance model of chronic pain posit that biopsychosocial factors can modulate pain. Non-pharmacological interventions are recommended in managing chronic pain, but little information is available regarding their efficacy in older adults. We examined and compared the efficacy of different non-pharmacological intervention approaches for chronic pain management among older adults via meta-analysis and subgroup analysis. RESEARCH DESIGN AND METHODS: Following the PRISMA guidelines (PROSPERO number CRD42020222767), a systematic search was undertaken using MEDLINE, Embase, and PsycINFO up to 21 March 2022. Randomized controlled trials were included, and data were pooled using a random-effects meta-analysis model. Risk of bias was assessed using a quality rating scale for psychological interventions. RESULTS: Twenty-five trials (N = 2394 participants) were identified. Six types of non-pharmacological interventions were compared with control conditions (sham/attention control and treatment as usual). Non-pharmacological interventions were associated with significant reductions in pain intensity, pain interference, depressive symptoms and catastrophizing beliefs and improvement in physical performance (standardized mean differences [SMDs] -0.34 to 0.54). Subgroup analyses based on different non-pharmacological approaches revealed the benefits of psychological approaches combined with physical activity. DISCUSSION AND IMPLICATIONS: Non-pharmacological interventions, particularly those adopting psychological approaches and physical activity, have a small but statistically significant effect on chronic pain management in older adults. Reduction in pain interference may be related to reduced catastrophizing beliefs, thus providing support for the fear-avoidance model. Further research with adequate power is needed to establish the efficacy and mechanism of various intervention modalities for older adults.
RESUMO
Background and Objectives: Health and mental health interventions, such as psychotherapy and exercise programs, delivered via information and communication technology (ICT) may improve service access. However, adjustment among older people and in synchronous group interventions is more challenging. Technology affordance concerns the possibilities engendered by technology for various users and purposes and can help understand challenges in ICT-delivered groups and identify possible solutions. Research Design and Methods: Adopting a multiple triangulation approach, we observed ICT-delivered groups of acceptance and commitment therapy and exercise for older people with depressive symptoms, conducted focus groups with older people who had received group psychotherapy with or without an exercise component, and obtained clinical notes from interventionists. We conducted a thematic analysis of the observation notes, focus group transcriptions, and clinical notes. Results: Four focus groups were conducted with 22 participants (mean age = 72.6 years, standard deviation = 7.2, 86% female). We identified 3 challenges: (1) seeing-be seen dilemma, (2) speaking-hearing dilemma, and (3) blurred therapy-home boundary, and 2 solutions: (1) maneuvering layouts and collaborative tools, and (2) cross-platform mediated strategies. Participants struggled to observe the interventionist while simultaneously demonstrating their posture in front of a camera. Remaining silent and moderated turn-taking allowed for clearer hearing but limited interactions. Interruptions from the background environment and intersections of family living spaces disrupted audio-visual communication and jeopardized the sense of security. As a solution, interventionists maneuvered layouts and collaborative tools on teleconferencing applications to achieve intervention goals and provided support through different media. Discussion and Implications: The identified challenges and potential solutions can be understood from interactivity, portability, temporality, persistence, and multimediality. Technology affordance can guide ICT-delivered group design by matching the affordance of various technologies and communication media with the characteristics of the intervention and users to enhance efficacy and avoid an unnecessary digital divide.
