The Children’s Anxiety Treatment Center (CATC)


The best design to answer evaluation questions

The Children’s Anxiety Treatment Center will be evaluated using a pre- and post-test. There will be no control groups in this design since each participant’s data will be considered as an independent unit (Fink, 2014). For the evaluation of the Children’s Anxiety Treatment Center, parents will be requested for informed permission from their children. Random identifiers will be issued to participants in order to protect their personal information. A record of treatment attendance will be preserved and used with the help of this number.

The pros and cons of the selected design

Because of the directionality of the research, the pre-test and post-test study design allows for assessment of a dependent variable (knowledge or attitude) before and after intervention with an independent variable. Because of the testing threat, the pretest-posttest control group design has just one disadvantage over the posttest-only control group design (Lohr, 2019). It is possible for this threat to arise when the pre-test and therapy interact.



Whether the selected design pose any additional ethical considerations

The parents of the participants will be notified of the assessment once they have been accepted into the program. In order to assess the program’s efficacy, they will be asked for their informed permission. The anonymity and confidentiality of the participants will be ensured by randomly providing each participant a unique identifying number. Prior to this, it will be easier to ensure secrecy and anonymity, as well as control over who attends treatment sessions (Fink, 2014).

The best sampling method for the selected population

The outcomes of this research will be generalized to a wide audience because of the non-probabilistic sample. Parents and children between the ages of 7 and 18 were included in the sample procedure (Lohr, 2019). Anxiety disorders were seen in children with and without autism spectrum disorder (ASD) (Fink, 2014).

The type of assessment schedule

Therapy participants will be assessed at the beginning and end of each session. In order to establish the program’s efficacy, the findings of the two evaluations will be compared.

The Adult Substance Abuse Treatment Program (ASATP)

The best design to answer evaluation questions

Single-Subject Designs will be used to study client-level outcomes. Using a single-subject case study in this research will allow us to evaluate the link between factors in ASATP and see whether the findings in the control group will statistically reduce substance usage and enhance the functioning of those participating (Fink, 2014). Objective measurements will be replaced by self-reporting methods.

The pros and cons of the selected design

There are several benefits to these designs, including their ability to be easily modified and their cost-effectiveness. There is a lot of emphasis on external validity and generalizability while doing research (Lohr, 2019). Because of the limited sample size, it might be difficult to extrapolate findings from single-subject designs to a broader population.

Whether the selected design pose any additional ethical considerations

When using the single-subject design, the practitioner/researcher should take in mind the ethical concerns of having enough information to determine the efficacy of social storytelling. The explanation is connected to the withdrawal of the intervention, a component of the design that may hurt the participant since returning to the baseline period is risky.

The best sampling method for the selected population

To get the intended findings, the researcher utilized a method known as purposive sampling (Lohr, 2019).

The type of assessment schedule

Before and after the program’s implementation, the participants will be assessed using the instrument designed for program assessment. The evaluator may use this approach to check whether the program has long-term effects, and it can give significant information on long-term effects (Fink, 2014).
