OBJECTIVE: To compare biologically targeted imagery (BTI) and critical thinking asthma management (CTAM) outcomes.
DESIGN: Participants were randomized to BTI (group 1, G1) or CTAM (group 2, G2) in a 2 x 2 x 4 design (BTI/CTAM x pretest/post-test x weeks [3 week averaged intervals of symptoms and peak flows]). Interventions were asthma education plus treatment (BTI or CTAM for two 2-hour sessions per week for 6 weeks). For BTI, data collection (symptoms, lung function) occurred preintervention (3 week baseline), during the intervention (6 weeks), and postintervention (6 weeks). For CTAM, data collection occurred at wait-list control (WLC) (12 weeks extended baseline), preintervention (3 weeks), during the intervention (6 weeks), and postintervention (6 weeks).
SETTING: Alaska Regional Hospital, Anchorage.
SUBJECTS: Seventy (70) adults (53 women, 17 men) with asthma.
INTERVENTIONS: WLC record keeping, BTI, or CTAM.
OUTCOME MEASURES: Dependent variables included asthma symptoms (wheezing, coughing, sleep, activity, attacks, peak flow) and self-report assessments of Profiles of Mood States (POMS-BI) (anxiety, hostility, depression, uncertainty, fatigue, confusion); Knowledge, Attitude, and Self-Efficacy Asthma Questionnaire (KASE-AQ); Health Attribution Test (HAT) for locus of control (LoC); and the Revised Asthma Problem Behavior Checklist (RAPBC).
RESULTS: Analyses of covariance with repeated measures contrasted BTI pre- to post-tests, time periods, and WLC; CTAM pre- to post-tests, time periods, and extended baseline WLC; and BTI to CTAM outcomes. WLC improved all POMS-BI scores except anxiety, increased internal LoC, and reduced problematic behaviors. Compared to WLC, BTI reduced wheezing, anxiety, and chance LoC, and increased asthma knowledge, attitude, and self-efficacy. Compared to CTAM, BTI reduced wheezing and chance LoC, increased internal LoC, and improved 6 POMS-BI scores. Compared to extended baseline WLC, CTAM increased asthma knowledge, attitude, self-efficacy, internal LoC, and peak flow.
CONCLUSIONS: Both interventions significantly improved symptoms and asthma management more than record keeping. Contrary to hypothesis, BTI produced better outcomes than CTAM.
