Understanding motivational factors related to physical activity (PA) maintenance is essential in promoting long-term exercise benefits. This study explored the impact of self-efficacy (SE) on post-intervention PA maintenance in patients with hip osteoarthritis.
An SE-theory based mixed-methods sub-study of a trial investigating the effects of 4 months supervised exercise in patients with hip osteoarthritis. Questionnaire data (n = 52; baseline and 12 months) on PA and SE (Arthritis Self-Efficacy Scale, ASES, score-range 10-100) were analysed (Mann-Whitney test) for differences in characteristics of maintainers and non-maintainers. Semi-structured individual interviews (n = 15; at 12-months follow-up) were analysed using directed content analysis.
Compared to non-maintainers (n = 9; 17%) maintainers (n = 31; 60%) had improved (p < 0.01) in median scores of ASES (Pain: +12 versus -32 points; Function: +7 versus -9 points; Other Symptoms: +11 versus -26 points) from baseline to 12 months. Experiences of possessing required skills, inspiration by other participants, encouragement from physical therapists and altered interpretations of PA-induced physiological conditions contributed to increased SE and PA maintenance. Moreover, experienced symptoms, exercise outcome expectations and obligation towards the study influenced maintenance.
SE contributes to understanding of post-intervention PA maintenance in patients with hip osteoarthritis. However, disease-related factors and clinical trial participation appears significant too. Implications for Rehabilitation Patients' perceived self-efficacy for physical activity contributes to the understanding of post-intervention physical activity maintenance in patients with hip osteoarthritis. Practitioners may benefit from incorporating the self-efficacy theory in the planning and execution of exercise interventions to promote post-intervention physical activity maintenance and long term health benefits. Post-intervention physical activity maintenance may be increased by focussing on the patients' exercise self-efficacy through verbal persuasion and support, disease-specific information and information on normal physiological responses to exercise combined with an individualised training progression to support experiences of success and achievement of desired outcomes.
了解与体育活动（PA）维持相关的动机因素对于促进长期运动益处至关重要。本研究探讨了自我效能感（SE）对髋骨关节炎患者干预后PA维持的影响。
一项基于SE理论的混合方法子研究，该子研究是一项试验的一部分，该试验调查了4个月的监督运动对髋骨关节炎患者的影响。分析了关于PA和SE（关节炎自我效能量表，ASES，得分范围10 - 100）的问卷数据（n = 52；基线和12个月）（曼-惠特尼检验），以比较维持者和非维持者的特征差异。使用定向内容分析法对15例患者（12个月随访时）的半结构化个体访谈进行了分析。
与非维持者（n = 9；17%）相比，维持者（n = 31；60%）从基线到12个月的ASES中位数得分有所改善（p < 0.01）（疼痛：+12分对 - 32分；功能：+7分对 - 9分；其他症状：+11分对 - 26分）。拥有所需技能的经历、其他参与者的激励、物理治疗师的鼓励以及对PA引起的生理状况的不同解读有助于提高SE和PA维持。此外，经历的症状、运动结果期望和对研究的义务感影响维持情况。
SE有助于理解髋骨关节炎患者干预后的PA维持情况。然而，疾病相关因素和参与临床试验似乎也很重要。康复的意义 患者对体育活动的自我效能感有助于理解髋骨关节炎患者干预后的体育活动维持情况。从业者可能会从将自我效能理论纳入运动干预的规划和实施中受益，以促进干预后体育活动的维持和长期健康益处。通过言语劝说和支持、疾病特定信息以及关于运动正常生理反应的信息，结合个性化的训练进展以支持成功体验和实现期望结果，关注患者的运动自我效能感，可能会增加干预后体育活动的维持。
