Treatment effectiveness of anxiety management training in small and large group formats.

Irrational beliefs, anger, and anxiety.

“…A comparison of the high-anger group (M = 367.51) to the pretreatment anger level of all of Novaco's (1975) subjects (M = 323.3) and of the control group of Hazaleus and Deffenbacher (in press;M = 334.74) revealed that the high-anger group was significantly more angry than were these groups, t(126) = 6.66, t(lll) = 3.94, ps < .001, respectively. A parallel comparison of the high-anxiety group (M = 48.53) with generally anxious college students (M = 50.06) from Daley, Bloom, Deffenbacher, and Stewart (1983) showed that the high-anxiety group was not significantly different from this treatment group, £(173) = 1.81. Personal perfection, anxious overconcern, blame proneness, and catastrophizing entered the regressions on the full distribution and extreme levels of anger, Ra = .54 and .70, ps < .001.…”

“…One study (Daley, Bloom, Deffenbacher, & Stewart, 1983) reported the impact of interventions on academic outcomes. This study found no significant effect of small group anxiety management training on improving grade point average.…”

Delivering group psychoeducational CBT in Primary Care: Comparing outcomes with individual CBT and individual psychodynamic‐interpersonal psychotherapy

“…Group CBT treatment has been found to be more cost effective than individual CBT (Lucas & Telch, 1993). Critics, such as Daley, Bloom, Deffenbacher, and Stewart (1983), have argued that larger group sizes may be unsatisfactory to clients. Both Butcher and de Clive‐Lowe (1985) and Carson, Cowan, Gill, and Titman (1988) reported that psychoeducational participants typically rate positive satisfaction, while Kellett et al (2004) indicated high levels of satisfaction for ‘stress control’ attendees.…”
