چکیده

مقدمه: در سال های اخیر علاقه به مطالعه تجارب توهمی و پدیدارشناسی آنها منجر به ایجاد ابزارهایی مانند مقیاس توهم لانای اسلد به منظور استفاده در جمعیت های بالینی و غیربالینی شده است. هدف از پژوهش حاضر، اعتباریابی و پایایی سنجی این مقیاس در نمونه ایرانی می باشد.
روش: این پژوهش از نوع توصیفی است. نمونه ای به حجم 312 نفر (88 نفر مذکر و 224 نفر مؤنث) انتخاب و در کنار 30 نفر از بیماران مبتلا به اسکیزوفرنیا مورد آزمون قرار گرفتند. شرکت کننده ها به پرسشنامه های مقیاس توهم لانای – اسلد، شخصیت اسکیزوتایپی و استعداد روان پریشی چپمن پاسخ دادند. داده ها با استفاده از روش تحلیل عاملی اکتشافی و تاییدی، آزمون تحلیل واریانس چند راهه و ضریب همبستگی پیرسون تجزیه و تحلیل شد.
یافته ­ها: در تحلیل مؤلفه های اصلی راه حل دو عاملی برای مقیاس توهم لانای – اسلد  استخراج شد، و به ترتیب عامل افکار مزاحم و رویاهای روزانه آشکار، و عامل تجارب توهمی شنیداری و دیداری نام گرفتند. در مقایسه نمرات گروه های مؤنث و مذکر، بین میانگین نمرات مقیاس تفاوتی مشاهده نشد. از نظر اعتبار تمایزی، مقیاس توانست بیماران مبتلا به اسکیزوفرنیا را از افرادسالم تفکیک نماید. اعتبار همزمان با اجرای توام پرسشنامه های مرتبط با نشانه شناسی مثبت روان پریشی ضرایب مطلوبی نشان داد. ضرایب پایایی به روش های همسانی درونی و بازآزمایی بالا محاسبه شدند.
نتیجه­ گیری: بنابر یافته های پژوهش حاضر، مقیاس توهم لانای – اسلددر نمونه ایرانی بعنوان ابزار سنجش تجارب توهمی اعتبار مطلوبی دارد و در تحقیقات مربوط به روان پریشی بعنوان یک ابزار معتبر قابل کاربرد می باشد.

چکیده [English]

Introduction:Recently an increased interest in the hallucinatory experiences and its phenomenology has resulted in a number of measuring tools for using in the clinical and subclinical population including the Launay-Slade Hallucinations Scale (LSHS). The aim of this study was to investigate validation and reliability of this scale among Iranian sample.
Method: The current study was descriptive research. A sample of 312 normal participants (88 male & 224 female) from university students and 30 patients with schizophrenia disorder took part in this research. Participants responded to Launay-Slade Hallucinations (LSHS), Schizotypal Personality Scale (STA) and Chapmans’s Psychosis Proneness Scales. Data were analyzed by explanatory and confirmatory factor analysis, multiple analyses of variance and Pierson correlation coefficient.
Results: Two factor solutions were extracted by Principal Component Analysis that named intrusive thoughts- vivid daydreams & auditory - visual hallucinations.  There were no sex differences among groups. Differential validity was tested by comparing Launay-Slade Hallucinations Scale (LSHS) scores between schizophrenic patients and normal people which was differential. Concurrent application of positive psychotic symptom questionnaires was used to calculate the convergent validity that showed acceptable coefficients. The internal constancy and test-retest reliabilities were found to be high.
Conclusion: Based on present study’s results, it was concluded that Launay-Slade Hallucinations Scale (LSHS) as a measure of hallucinatory experiences contain good validity and reliability in Iranian population and it can be used as valid measure in researches related to psychosis.
