Question

Based on abstract: How would a one-way ANOVA test be appropriate? severe mental illness : This research study aims to explore the relationship between quality of life (Col) adopting a prospective, naturalistic, longitudinal follow-up research design, a participated in a community-based psychosocial program were followed for one and 12-month follow up assessments. At the 12-month follow up, this cohort of and recovery in mental illness in a community-based psychosocial program. By cohort of 87 consumers who were discharged from mental hospitals and year. Qol and recovery of these individuals were assessed at baseline, 6-month participants showed improvement in QoL and achieved a recovery rate of 8%. ANOVA analysis indicated that overall QoL was not related to recovery. Moreover, multiple linear regression analysis showed that overall QoL was predicted significantly by self-efficacy at baseline, improvement in self-efficacy and improvement in functioning (adjusted R2 = 228,F(3,81) = 9.272,p

Explanation / Answer

Pre-requisite of running One way ANOVA model is

a) Dependent variable continuous in nature i.e.

b) Independent Variable categorical in nature(with more than 2 categories)

Looking at the table, we could see Overall QoL for different timeframes i.e. t1,t2,t3.

Hence ANOVA could be conducted.

Now, as per the tabled data, Overall QoL has improved against all the 4 domains i.e QoL Phy, Psy, Soc & Env.

We can refer to the Remarks section listing in which timeframe the QoL has improved.

For ex: QoL Phy. domin = Significant improvement in QoL is happened b/w t1 & t2 and t1 & t3 whereas no such significant improvement is recorded between t2 & t3.

Since the study is quoting that Recovery Rate is not linked to QoL. We need additional data to justify the same.

Based on the data provided we can only confirm that QoL score improved significantly.
