摘要:

Establishing treatment implementation (TI) involves precise description of the intervention and accurate assessment of the intervention's usefulness in promoting therapeutic change. To be considered successful, treatments must be accuratelydeliveredby therapists, understood (orreceived) by clients, and used (orenacted) by clients in their everyday lives. Our goals in this article are (a) to describe the 3 components of TI: treatmentdelivery,receipt, andenactment; (b) to provide specific examples of the assessment of TI in published intervention studies involving Alzheimer's and non-Alzheimer's samples; and (c) to provide practical recommendations for the use of TI measures in research and practice.

摘要:

Validity can be defined as the approximate truth of an inference, proposition, or knowledge claim. Using a validity typology that is relevant to the design of field experiments, we describe 4 types of validity—statistical conclusion, internal, construct, and external. We stress that the decisions made by researchers regarding validity cannot be made in a vacuum but must reflect an understanding of the research problem, its proposed solutions, as well as the population or setting being studied. Drawing upon examples from caregiving intervention studies, we demonstrate how an understanding of validity can be used to help understand results from studies as well as how to think about planning services and designing new evaluations.

摘要:

In recent years a wide variety of intervention approaches have been developed to alleviate burden and distress among family caregivers. Generally, the literature suggests that these interventions have been moderately successful in reducing outcomes such as caregiver burden, depression, anxiety, and distress. Most of the reported findings are based on statistical significance or effect size statistics. To date little emphasis has been given to the clinical significance or practical relevance of intervention outcomes. The objectives of this paper are to (1) define the construct of clinical significance and review existing methods for measuring clinical significance, (2) discuss strategies for maximizing clinical significance, and (3) outline other issues such as cost-effectiveness that need to be considered within intervention research. Our overall goal is to extend our understanding of methods for evaluating the effectiveness of interventions to improve the quality of intervention research.
