The strengths of this research are worth noting: firstly, by using a systematic review design and meta-analysis approach it ensured that any bias introduced into the data during selection process have been minimized; secondly, it used an extensive search strategy which allowed for comprehensive coverage of all relevant studies published up until 2017; thirdly, results from all analyses are presented clearly providing readers with detailed information regarding effect sizes for primary outcome measures for each comparison within the meta-analyses.

However some limitations should also be noted: firstly the quality assessment tool used had not been formally validated meaning there is potential issue here with reliability; secondly due to heterogeneity across studies there may be issues related confounding factors such as comorbidities affecting outcomes which were not controlled for; thirdly since many studies included had small sample sizes this could lead to possible overestimation/underestimation effects impacting on results obtained from meta-analyses carried out making their interpretation difficult if not impossible at times (in terms if they being considered clinically useful). Despite these limitations though the findings remain valid due their statistical power indicating significant reductions in overall composite scores associated more specifically with depressive symptoms seen when comparing treatments against control groups/conditions respectively throughout respective comparisons made within analysis undertaken during course of study’s duration – suggesting that intervention being studied can indeed enhance overall patient welfare significantly particularly vis-à-vis depression symptomology reported amongst subjects tested who received cognitive behavioral therapies evaluated during course thereof .

In conclusion then given evidence reviewed above current practice should involve use Cbt modelling where appropriate instead traditional psycho dynamic models commonly employed currently especially where optimizing response rates associated specifically depressive disorders amongst patient populations being treated therein concerned partaking same – ultimately leading improved outcomes both short term long-term respect posttreatment period thus meriting further research future formulating more robust recommendations clinical application based evidence produced through such investigations going forward .
