[Influence of social support and personality traits on psychological characteristic of patients with chronic cervicodynia and lumbodynia].

OBJECTIVE: To explore the effects of social support and personality traits on psychological characteristic of patients with chronic cervicodynia and lumbodynia and improve the level of diagnosis and treatment. METHODS: From August 2009 to April 2010, 231 patients (obtained 217 effective responses) with chronic cervicodynia and lumbodynia were recruited. Among the patients, there were 123 males and 94 females, with an average age of (38.00 +/- 5.67) years (ranged from 15 to 66 years). Social Support Rating Scale (SSRS), Cattell Sixteen Personality Factor Questionnaire (16PF) and Symptom Checklist 90 (SCL-90) were used to test social support and psychological characteristic and compared the difference of psychological, personality traits and norm, then analyzed the effect of social support and personality traits on psychological characteristic. RESULTS: Two hundred and seventeen (93.9%) patients completed the questionnaire. Compared with normal 16PF scores, there were significant differences in factor scores of intelligence, stability, excitability, perseverance,social boldness, vigilance, sophistication, experimental, independence and tonicity (P < 0.01). And for SCL-90, the score of somatization, depression, anxiety, rivalrounsness, horror, bigotry, total score and mean score were higher than norm (P < 0.01). For SSRS, subjective support points and total points had positive effects; While intelligence, stability, perseverance, self-discipline had positive effects, vigilance and anxiety had negative effects. CONCLUSION: There were significant differences in personality traits and psychological characteristic between patients with chronic cervicodynia and lumbodynia and norms. Improving social support level and optimizing personality traits can improve psychological profile of these patients.

Effects of field-dependent cognitive style on optokinetic illusion.

OBJECTIVE: To study the effects of the field-dependent cognitive style on optokinetic illusion. METHOD: One hundred military university students were tested with Rod and Frame Test. Fifteen high score subjects and 15 low score subjects were arranged into field-dependent group and field-independent group respectively. Each subject experienced a series of optokinetic step stimulation (5, 10, 15, 20, 30, 40, 60, 80, 100, 120 degrees/s) for 20 s. The latent period and fuzzy estimate magnitude of the illusion were recorded. RESULT: The results obtained were as follows: 1) The latent period in the field-dependent group were shorter than that in the field-independent group, and decreased exponentially with the stimulation. The latent period in the field-independent group decreased linearly with stimulus; 2) Between 5-120 degrees/s, the fuzzy magnitude of the two groups regressed to two linear equations, no significant difference was found between the coefficients of two equations, but the intercepts were significantly different. CONCLUSION: Cognitive style was found to be an important influencing factor on optokinetic illusion. People with the field-dependent cognitive style were susceptible to optokinetic illusion.
