Sci. & Agric., 9(6): 2649-2653, 2014 INTRODUCTION Obsessions are a central feature of Obsessive-Compulsive Disorder (OCD) and worry is the central characteristic of Generalized Anxiety Disorder (GAD) (Langlois et al. 2000). Because of these common disorders are characterized by excessive and uncontrollable cognitive processes associated with negative affect, these disorders might be considerable overlap with together (Van Rijsoort et al. 2001). Worry and obsessions have some similar characteristics; for example;(a) both phenomena occur in normal as well as patient populations, (b) the form and content of worry and obsessions appear to be similar in normal and clinical groups; (c) both occur with greater frequency and are associated with greater perceptions of uncontrollability in clinical populations than in normal groups; (d) both worry and obsessions are associated with adverse mood; and finally (e) that same type of vulnerability factor determines why individuals develop pathological worries or obsessions and others do not (Turner et al. 1992). However, apart from these similarities, worry and obsessions appear to differ to a great extent on several dimensions. Worry usually concerns normal life circumstances whereas the content of obsessions tends to be more bizarre (Brown et al. 1994). Also, even though both are characterized by perceived uncontrollability, at least in clinical cases, worry is more likely to be perceived as self-initiated. Recently, an attempt has been made to distinguish between worry and obsessive-compulsive symptoms in terms of process characteristics and meta- Meta worry (Clark, & Claybourn. 1997).

2650 Khankhani Zadeh et al, 2014 Several self-report instruments have been developed to assess worry. These include the Penn State Worry Questionnaire (PSWQ), Anxious Thoughts Inventory (AnTI) and the Worry Domains Questionnaire (WDQ). The Penn State Worry Questionnaire (PSWQ) is the measure most frequently used to assess pathological worry in both clinical and non-clinical populations. Several researches support the use of the PSWQ in screening individuals likely to meet criteria for GAD (Frescoet al. 2003). An instrument that is gaining popularity in the measurement of obsessive-compulsive (O-C) symptoms is the Padua Inventory (PI; Sanavio, 1980). Although Sanavio (1980) in his original study reported that the PI can differentiate between OCD patients and neurotic patients, to date, there is not enough evidence to conclude about the validity of the PI in samples of participants with clinically diagnosed OCD. Burns and et al. (1995) reported that individuals who scored high on the PI also reported more depression and Generalized Anxiety Disorder. In addition, many reports indicates that the PI measures worry in addition to obsession (Freeston et al. 1994; Burns et al. 1996; Goodarzi & Firoozabadi. 2005). This is especially true for two impaired control and checking subscales (Goodarzi & Firoozabadi. 2005). These results indicate that some items of the PI measure non-specific elements of OCD and the PI measures worry and obsessions. However, it has been noted that measures of worry and obsessive present a number of limitations to researchers wishing to distinguish between worry and obsessions and wants to explore the differences between these types of ideational events (Burns et al. 1996). According to these results, to facilitate research, self-report instruments that reliably distinguish between worry and obsessions are required. The present study aimed to further explore the relationship between worry and O-C symptoms. We examined differences between the GAD and OCD patients with TAF and PSWQ to explore further distinctiveness. 1. Methodology: 1.1. Participants: Twenty-five adults with OCD, twenty-five adults with General Anxiety Disorders and twenty-five adult normal people participated in the study. The patients were selected from Taleqani Hospital (Evin, Tehran, Iran) by the authors and a psychiatrist using DSM-IV criteria for diagnosis. Patients are selected as our sample using availability sampling. Those patients who were taking psychoactive drugs during a 4-week period before examination in the study were excluded. Patients with OCD were matched with GAD patients and normal participants according to the following variables: age, education and gender. The normal group consisted of hospital support staff and community volunteers who denied any history of psychiatric treatment and did not meet criteria for any DSM-IV Axis I disorder as determined by the SCID-IV. 1.2. Measures: 2.2.1. Thought Fusion Instrument: Thought action fusion (TAF) Scale (Wells et al, 2001), is a self-report scale that has 14 item and measures people s beliefs about thoughts, risk and consequences of their thoughts according to metacognitive model. Scores range of scale are between 0 to100 measured. This scale measures three beliefs: thought action fusion (TAF), thought event fusion (TEF), thought - object fusion (TOF). The reliability and validity of this scale had been good reported (J. Williams et al, 2004). 1.2.2. Penn State Worry Questionnaire (PSWQ): The Penn State Worry Questionnaire (PSWQ; Meyer et al. 1990) is a 16-item self-report scale that measures tendency to worry. Responses are requested on a five-point scale with 1 representing not at all typical to 5 very typical. The PSWQ is a reliable and valid measure for clinical and non-clinical groups. The PSWQ has good internal consistency with Cronbach s alphas ranging from.86 to.93, and good test retest reliability with reported coefficients ranging from.74 to.93 (Meyer et al., 1990). The validity and reliability of PSWQ for the Iranian population were established by Shirinzadeh Dastgiri (2006). 1.3. Procedure: First, the researcher explained the aim of study to the subjects after the diagnostic assessment by a trained clinicians and then asked them to participate if they agree, arranged to administer the in a private room in the hospital. The questionnaire packet containing the two measures was organized in a counterbalanced format. Multiple orderings were created by placing the Worry and OCD instruments in varying orderings across the whole sample (i.e., each group was equally varied in first or second, place for of two orderings). Participants were tested individually and so filled the questionnaires. 3. Results: To provide a clearer picture of the demographic characteristics of participants, descriptive data's were analyzed. Demographic are show in Table 1. Table 1 show the age and education mean for the three studied groups as can be seen in the Table 1, the three participant group did not differ in terms of age or Education. Also

2651 Khankhani Zadeh et al, 2014 ANOVA results showed that there weren't significant difference age and educational mean between GAD, OCD and normal groups. One way analysis of variance (ANOVA) was used in order to comparing of between groups differences in thought-action fusion (TFI) scores and Meta worry (PSWQ) subscales. The results showed that there was a statistically significant difference between the groups Thought-action fusion. Bon Feroni Post hoc tests to compare of pairs means showed that there is not significant different between GAD and OCD groups in thoughtaction fusion beliefs and Meta worry. Nevertheless however, thought-action fusion and Meta worry beliefs were significantly difference between GAD and OCD patients in compare with normal group (Table 2).

Discussion: The aim of this study was to evaluate and compare the thought-action fusion and worry among patients with generalized anxiety disorder, Obsessive - Compulsive, in compare with normal people. Statistical appropriate methods and multivariate variance ANOVA and post hoc tests were used for research data analysis, as. ANOVA results showed that there was a significant difference between the GAD and OCD and normal groups in thought action fusion. However, thought-action fusion subscales were significantly difference between GAD and OCD patients in compare with normal group. Thus, it is corollary that thought action fusion is a belief that led to increase of catastrophic impressions in emotional disorders. These findings are in line with other research (Aynstyn and Mnzys, 2004; Bramvvytz et al, 2003). Multivariate analysis of variance (MANOVA) Results showed that there were significant difference in the all of thought action fusion (TAF), thought event fusion (TEF) and thought Object fusion (TOF) subscale between GAD and OCD and normal groups. But pair means comparing by Bon Feroni Post hoc tests showed that there weren't significant different between GAD and OCD groups in thought-action fusion beliefs and Meta worry. However, thought-action fusion and Meta worry beliefs were significantly difference between GAD and OCD patients in compare with normal group. Nevertheless, these findings are consistent with Wells' metacognitive model of emotional disorders. Thought about worry involves this belief that worry can affect all external events. In a study of patients with generalized anxiety disorder expressed concern that the employment probability of occurrence of bad events that have been predicted to reduce (Bvrkvyk and Romer, 1995). Cognitive belief structure about worry is very similar to possible thought action fusion that assume think about the action- event is put forward as positive beliefs about worry and generalized anxiety disorder is research showing the correlation between belief and GAD or OCD (Bvrkvyk et al, 1999). ANOVA results of Comparing worry between GAD, OCD, and normal group indicated that there were significant differences among them. Compare of pairs means by using Bon Feroni test showed that both GAD and OCD groups are significantly different from normal subjects in worry, but wasn't found difference between patient groups. These results are consistent with cognitive models of Wales (2000) and freshwater research and Shirinzadeh (2006).

2652 Khankhani Zadeh et al, 2014 Given that rumination and negative thoughts such as obsessive or anxiety keeping with their ego-dystonic nature. So, worry and rumination is associated with the preventing and avoiding motive of hazards. Therefore it as seen by concerned and obsessed person perspective as a coping strategies, and by continuing of worry and rumination and inability to control of it, worry becomes the center of the patient's concerns (Wells and Matthews, 1996). Nevertheless appears to be increasing trying to suppress of worry and rumination in frequency and salience of negative thoughts (Becker et al, 1998). 5. Conclusion: This study showed that the differences between GAD and normal peoples in worry and Thought -action fusion subscale was significant (Table 2, 3). This result is comparable with the findings of Wells and Papageorgiou (1998). Also results of this research indicated that patients with OCD have scored (77) higher than normal participants (NP-49) and GAD (70) patients in the total score of the worry. The ANOVA Test revealed a significant difference among three group (table 2). But there were no difference between OCD patients and patients with GAD in total score of the TAF and their subscales (see Table3). This finding shows that the TAF score does not measure purely specific features of the OCD patients. Accordingly, the TAF appears to be a useful measure for differentiating OCD patients and nonclinical OCD cases from normal people. However, its usefulness in differentiating between OCD patients and patients with anxiety disorder (GAD) has not been supported by our findings. Further refinement of the TAF is necessary to enhance specificity of measurement and discriminant validity of the instrument. This conclusion is comparable with the findings of other studies which show the TAF score cannot differentiated between OCD and anxious patients (Burns et al. 1995; Goodarzi, Firoozabadi. 2005; and Sternberger. 1991). However, some of the positive correlation between worry and compulsive symptoms may be substantive, thus indicating potentially important concept links between worry and compulsive behaviors. Wells and Morrison (1994) demonstrated that normal individuals could make a valid distinction between normal worries and obsessions when provided with a simple definition. Such an approach could be adopted for future revision of the Worry. In particular, the ego-dystonic nature of obsessions should be highlighted. Other key differences between worry and obsessions could be also be emphasized in a revision of instructions for scale (Wells and Papageorgiou. 1998). For instance Wells and Morrison (1994) showed that obsessions were more telegraphic than worries and were more involuntary. An emphasis on such features may increase the specificity of the Worry.
