Title: Developing and Evaluating the Efficacy and Feasibility of Delivering a Psychoeducational Individual Intervention to Women with Advanced Stage Ovarian Cancer: A Two Phase Study
Author: Doyle, Kimberly Cecile
Abstract: Method : This study was conducted in two phases . Phase I consisted of a psychosocial needs assessment (n = 15 ) to determine the appropriate elements necessary for inclusion in an individual intervention . Perceived barriers to participation in psychosocial services , including group support , were also assessed . The outcome of the needs assessment combined with an extensive literature review was used to develop the Phase II intervention . In Phase II , participants (n = 30 ) were recruited from the gynecologic oncology practice at Baylor Sammons Cancer Center . Participants were randomized to intervention (n = 15 ) vs . control (n=15 ) groups . Intervention sessions lasted 60 minutes and were conducted weekly over a period of 8 weeks . Sessions consisted of a combination of education and psychosocial support . Growth modeling was used to evaluate variation in within -individual rate of change in outcome measures during the treatment (weeks 1 -8 ) and followup (weeks 16 -48 ) periods of the study . Repeated measures ANOVA was used to evaluate average group differences in outcome measures during the treatment and follow -up periods of the study . <strong >Results : < /strong > No main effects of time , group , age , or education were observed with regard to rate of change of psychosocial adjustment to illness during the treatment period of the study using growth modeling . However , during the follow -up period of the study , time and group were significant predictors of within -individual variation in rate of change in psychosocial adjustment to illness . Similarly , repeated measures ANOVA yielded no main effects of time or group in psychosocial adjustment to illness during the treatment period of the study ; however , a main effect of group (p < .05 ) and an interaction between group and time (p < .05 ) were noted during the follow -up period of the study with the most significant differences in group means occurring at week 48 (effect size = .70 ) . Although not stable across all models created , time was the only significant predictor of within -individual variation in rate of change in depression symptoms during the treatment and follow -up periods . A main effect of time without consideration of group (p < .01 ) and an interaction between group and time (p < .01 ) with regard to depression symptoms was noted in the treatment phase of the study , most significantly at week 8 . A main effect of group (p < .05 ) , most significantly at week 48 , was observed during the follow -up phase (effect size = .69 ) . Similar to depression scores , withinindividual variation in anxiety symptom scores was significantly predicted by time during the treatment period of the study . Although no main effects of predictors were observed with regard to anxiety symptoms during the follow -up period of the study , the model with the greatest goodness of fit included the predictors education , group , and time . Repeated measures ANOVA suggest a main effect of time (p < .05 ) with regard to anxiety symptoms during the treatment period of the study but no main effect of group . However , during the follow -up period of the study , a main effect of time (p < .05 ) and group (p < .05 ) were noted with regard to differences in the average state anxiety symptom score between groups , with the most significant difference occurring at week 48 (effect size = .43 ) . Cost analyses suggest minimal differences in the number of medical office visits and phone calls between groups and a moderate difference in usage of psychiatric and pain medication between groups . Treatment satisfaction was high across all intervention topics , with participants rating sessions 1 and 8 the most helpful . <strong >Research and Clinical Implications : < /strong > Concordant with the literature , the results of this study suggest that individual interventions wi
