Identifying thecausal relationship between the variables could facilitate the design of preventiveinterventions. Future studies could focus on the causal relationship betweenparanoid thoughts and attributions in longitudinal and experimental models. Wedid not compare different groups with respect to social perception. Futurestudies could also assess this variable.
Since the present study was the first part of thethree-phase project of the Ph.D. thesis, which included the implementation ofthe protocol of treatment and follow-up evaluation, the main limitation of the present study is our smallsample size due to the intricacy of recruiting and withholding of thechronically schizophrenic patients (as our main inclusion criterion) throughoutof an 3-month protocol with emphases on dailyparticipation which consequently pursued by a 4-monthfollow-up evaluation. The issue which can lead to an increased risk of type Ierror and of course, our freedom at the entrance of related variables in theregression analysis is reduced. It should also be acknowledged that there areundoubtedly many other important variables that go beyond what is considered inthis study; Variables such as IQ, cognitive emotional regulation strategies andso on which might provide important insights that could specify the effectsobserved on social cognition as a multi-dimensional construct.
Conclusion:Despite these limitations, this study encourages us toconsider paranoid in time of studying cognitive social degradation in peoplewith schizophrenia, specially paranoid type. Our findings also suggest thatsocial problems in people with paranoid schizophrenia are likely to be greaterthan those with Schizophrenia which the later may benefit from more specificinterventions. Finally, this study motivates us, to consider socialcognition dimensions, this time in the population of other patients who are whichthe Psychotic symptoms constitute an important part of their clinicalpresentation (like Bipolar disorders or schizotypal personality disorder) inour future research.
