The other relationships were not found to be significant. The model advanced by the researcher was found to explain only 17% of the variance observed in the dependent variable.
This particular study presented what might be considered a new approach to addressing the issue of physical discipline in immigrant communities. The deliberate use of a skewed population while it may amplify the effect of the phenomenon that is being studied weakens the generalizability of the study. Thus, the author's decision to employ a purposive sample design tremendously weakens the overall validity of the work. Additionally, because of using a non-probability type sample design the author is unable to determine effectively the quantum of error in the study this adds to the overall weakness of the approach (Kitson et al. 1982, p.967).
It should also be noted that the explanatory power of the model tested by the researcher is low. This means that the researcher did not examine the powerful variables; this is very intriguing...
It is highly probable that if a probability type design is used without a biased sample the effect may be even smaller. Consequently, the study is not compelling enough to demand that practitioners make changes to their behaviors at this time. One of the most praiseworthy elements of the work is the researcher's commitment to integrity and accountability. The researcher noted several limitations of the work, which included that statement work, could not be generalized to a wider population. This is commendable.
