Measuring Community Impact using the Zimbabwe Community Life Questionnaire (ZCLQ)
As part of an Impact Evaluation exercise conducted in 2012, TOL and CVT created the Zimbabwe Community Life Questionnaire (ZCLQ) - a tool which measures positive change in community engagement, contributions to the lives of others, and attitudes to community healing - as reflected in increasing scores.
Data is analysed using “significance testing / effect sizes” before and after the intervention
- Effect sizes of 0.2 – 0.5 show that the intervention had a small impact
- Effect sizes of 0.5 – 0.8 show that the intervention had a meaningful/moderate impact
- Effect sized of 0.8 and above show that the intervention had a large/significant impact
2018
Analysis of 597 clients assessed in 2018 shows the effect size of 0.9, indicating ‘significant change’ in the lives of our participants. The mean score also increased from 3.82 (out of 5) before the healing workshops, to 4.43 at follow-up.

2017
The effect size realized is an impressive 1.05, indicating ‘significant change’ in attitudes to community life, after the TOL healing workshops. The mean score also increased from 3.80 (out of 5) before the healing workshops, to 4.49 at follow-up.

2015
254 clients were assessed with the ZCLQ-28 before and after healing and empowerment workshops in 2015. Analysis of the data seen below shows that the Tree of Life intervention DID produce statistically significant positive change in community engagement, contribution to the lives of others, attitudes to community healing – these results were independently verified by CVT.

Example of a few ZCLQ questions
The ZCLQ contains 20 questions that help to measure community connectedness. ZCLQ assessments are done before the healing workshop and 3 months after. Higher scores indicate more connectedness and cohesion. Below are some examples of ZCLQ questions
