Background: The International Psychogeriatric Association Task Force on Mental Health Services in Long-Term Care Facilities aims to support and strengthen mental health services in the long-term care sector. The purpose of this paper is to identify broad principles that may underpin the drive towards meeting the mental health needs of residents of long-term care facilities and their families, as well as to enhance the overall delivery of residential care services.

Methods: Principles of good care are extrapolated from an analysis of international consensus documents and existing guidelines and discussed in relation to the research and practice literature.

Results: Although the attention to principles is limited, this review reveals an emerging consensus that: (1) residential care should be situated within a continuum of services which are accessible on the basis of need; (2) there should be an explicit focus on quality of care in long-term care facilities; and (3) quality of life for the residents of these facilities should be a primary objective. We take a broad perspective on the challenges associated with actualizing each of these principles, taking into consideration key issues for families, facilities, systems and societies.

Conclusions: Recommendations for practice, policy and advocacy to establish an internationally endorsed principles-based framework for the evolution and development of good mental health care within long-term care facilities are provided.

Objective: This study aimed to clarify which older adults benefit most from a control-enhancing intervention; in particular, whether cognitive functioning or locus of control might moderate the benefit derived.

Methods: Nursing home residents were randomly assigned to two conditions: (1) a control-enhanced condition that provided the option of caring for a plant (n = 10), and (2) a comparison condition that monitored any change under the standard of care (n = 10). Comparison group participants were subsequently offered the intervention, which led to a total of 17 intervention participants.

Results: Cognitive function and locus of control were found to significantly moderate the effects of the control-enhancing intervention on residents' perceived health competency, but not depression or life satisfaction.

Significance of results: Interventions for nursing home residents could be tailored to fit specific needs. Screening for cognitive function and locus of control may help predict who is likely to benefit from control-enhancing interventions.
