Triangulation reveals theoretical linkages and outcomes in a nursing intervention study

CNSs ROUTINELY GIVE psychosocial support to patients dealing with life-threatening illnesses. Yet few studies discuss theoretical aspects of psychosocial support. The purpose of this paper is to report results of a study using an efficacy-enhancing intervention given to 49 patients receiving chemotherapy for cancer. Analysis of qualitative data revealed (1) linkages of a supportive psychosocial intervention with the theoretical basis of the study and (2) outcomes not apparent in statistical analysis of the hypothesis-testing study. Interventions were based on Orem's self-care framework and Bandura's description of sources of efficacy expectations. Data triangulation to identify areas where previous findings had not revealed interpretations provided a different perspective on the same phenomena and led to revisions in further study. Implications for CNS practice and research are discussed.
