Grip strength and quality of life in the second half of life: hope as a moderator.

OBJECTIVES: The purpose of the current study was to investigate grip strength, hope, and their interaction as predictors of quality of life four years later in a nationally representative sample of older adults. METHOD: Data were derived from the first (2005-2006) and second wave (2009) of the Israeli component of the Survey of Health Ageing and Retirement in Europe (SHARE; N = 344). Hope was measured by three items from the Hope   Scale, and quality of life was measured by the CASP-12 (Control, Autonomy, Self-Realization, and Pleasure). Multiple regression analyses were conducted. RESULTS: Grip strength at T1 predicted QoL in T2, but hope was not a significant predictor. Furthermore, hope moderated the effect of handgrip on QoL, such that the effect was weaker for higher levels of hope. CONCLUSION: As hypothesized, hope acted as a moderator, such that poor grip strength was associated with worse QoL for less hopeful older adults, but grip strength was not associated with QoL for more hopeful older adults. Findings are consistent with a theoretical conceptualization of hope as a buffer between physical challenges and negative outcomes like QoL. Encouraging a hopeful perspective could enhance QoL for older adults with decreased muscle strength.

Physicians' cognitive strategies for avoiding overconfidence.

BACKGROUND: Physicians' overconfidence damages the quality of medical care. Due to their high social status and intense impact on people lives, physicians need to develop strategies to avoid overconfidence. Yet until now, the strategies physicians use to avoid overconfidence have not been explored. This study aimed to identify strategies physicians use to minimize potential overconfidence. METHODS: This qualitative study relied on face-to-face semi-structured interviews. Participants were 22 physicians specializing in ophthalmology, gynaecology, rheumatology, cardiology, anaesthesiology, paediatrics, radiology, orthopaedics, otolaryngology, gastroenterology, family and paediatrics. The interviews were analyzed with the grounded theory approach. RESULTS: Analysis of the interviews revealed three prominent strategies physicians use to minimize overconfidence: awareness of the risks of overconfidence, framing a mundane professional identity, and cultivation of a positive self-view through pride based on effort rather than skills. CONCLUSIONS: The study demonstrates the on-going nature of establishing physicians' professional identity and implies that it is shaped by a motivation to adapt their identity to fundamental requirements of medical practice. Medical training and education might promote strategies for minimization of potential overconfidence among physicians.
