Psychological Factors Predicting Functional Ability and Participation After Hip Fracture

Abstract

Importance: Positive psychological factors have been related to better outcomes among adults with various health conditions.

Objective: To predict functional ability and participation in older adults who had experienced a hip fracture on the basis of data at admission to acute (inpatient) rehabilitation. We measured physical factors, as well as positive and negative psychological factors, at three time points.

Design: Prospective and cross-sectional cohort study. Data collection occurred during admission, at discharge, and 6 mo after rehabilitation.

Setting: Inpatient geriatric rehabilitation center and follow-up at home.

Participants: Seventy-one older adults (M age = 78.58 yr, SD = 6.09) who had sustained a hip fracture because of a fall and who attended acute rehabilitation; 55 completed follow-up assessments 6 mo after discharge from rehabilitation.

Measures: Participants completed the Adult Hope Scale, Life Orientation Test, Positive Affect Questionnaire, Geriatric Depression Scale (at admission only), hand-grip strength measures, Numeric Pain Rating Scale, and FIM® Motor domain (mFIM) before and after acute rehabilitation and after 6 mo. The Activity Card Sort (ACS) was administered only at follow-up. Outcome measures were the mFIM and ACS.

Results: At 6-mo follow-up, functional ability was correlated more with optimism than with age, gender, or hand-grip strength measured at admission. Participation was predicted by age, the hope-agency component, and pain in walking at admission; however, the hope-agency component was only marginally significant. At discharge, functional ability was strongly predicted by age, hand-grip strength, and mFIM scores at admission.

Conclusions and relevance: Optimism and hope played a role in explaining rehabilitation outcomes at 6-mo follow-up. Occupational therapy evaluation should address positive psychological factors, and intervention should aim to strengthen these factors as powerful aids in older adults' recovery from hip fractures. What This Article Adds: This study reflects the philosophy of occupational therapy, which places great emphasis on the connection between clients' mind-body-spirit and their participation in daily life occupations.
