Objective:To explore the influence of chronic rhinitis on depressive symptoms of college freshmen and the mediating effect of avoidant personality.Methods:A cluster sampling method was used to survey 8 079 college freshmen from April 2018 to October 2018 using the Beck depression inventory and the avoidant personality diagnosis questionnaire based on DSM-Ⅳ.SPSS 25.0 software was used for descriptive statistics and Spearman correlation analysis, and the macro program PROCESS version 3.3 was used for the mediating effect.Results:(1) The detection rates of chronic rhinitis, avoidant personality and depressive symptoms were 22.90% (1 850/8 079), 19.22% (1 553/8 079) and 6.28% (507/8 079). The scores for avoidant personality disorder and depressive symptoms were 1.00 (0, 3.00) and 1.00 (0, 4.00), respectively. (2) The chronic rhinitis, avoidant personality and depressive symptoms were positively correlated ( rchronic rhinitis-avoidant personality=0.094, rchronic rhinitis-depressive symptoms=0.095, ravoidant personality-depressive symptoms=0.416, all P<0.001). (3) Chronic rhinitis could positively predict depressive symptoms ( β=1.113, P<0.001). (4) Avoidant personality played a mediating role between chronic rhinitis and depressive symptoms ( β=1.094, P<0.001), and accounted for 44.92%(0.500/1.113) of the total effect. Conclusion:Chronic rhinitis directly affect the depressive symptoms of college freshmen, and indirectly affect the depressive symptoms of college freshmen through the mediating role of avoidant personality.

The Differential Profile of Social Anxiety Disorder (SAD) and Avoidant Personality Disorder (APD) on the Basis of Criterion B of the DSM-5-AMPD in a College Sample

@#Background: The present study was conducted to determine the differential profile of social anxiety disorder (SAD) and avoidant personality disorder (APD) based on dimensional diagnosis in criterion B of the DSM-5 Alternative Model for Personality Disorders (DSM-5-AMPD) in a college sample. Methods: Samples of this cross-sectional study included 320 (23.08 ± 2.66 years; 57% female) college students in western Iran during February 2015 to December 2017. Liebowitz-social anxiety scale, PID-5, SCID-II, SCID-II-SQ and diagnostic interview for SAD were the tools. The data were analysed using Pearson correlation and multiple linear regression analysis. Results: Forty-three and 38 participants met criteria for SAD alone and APD, respectively. Five main domains of PID-5 could explain 29% and 54% of the variance of SAD and APD, respectively. Facets of negative affect, detachment, antagonism, disinhibition, and psychoticism could explain 25% versus 43%, 26% versus 54%, 7% versus 27%, 21% versus 41%, 13% versus 30% of the variance of SAD and APD, respectively. Conclusion: SAD and APD probably refer to two distinct mental states having prominent anxiety, emotional instability, and interpersonal pattern of avoidance and detachment of challenge. SAD is a simple form of mental disturbances with anxiety in its core features; although, APD is possibly referring to more complicated psychopathology.

The Mediating Effects of Loneliness on the Relationship between Smartphone Addiction and Dependent Personality Trait in Adults

BACKGROUND: As the number of smartphone users is increasing, smartphone addiction is a recent concern. The purpose of the present study was to examine the mediating effect of loneliness on the relationship between smartphone addiction and dependent/ avoidant personality trait in Adults. METHODS: A total of 550 adults (male 116, female 434) were selected and rated smartphone addiction scale, dependent and avoidant personality trait scales, and loneliness scale. Pearson correlation coefficients, Structural Equation Model Analysis and Sobel test using SPSS version 21.0 (IBM, New York, NY, USA) and AMOS version 21.0 (IBM, New York, NY, USA) were conducted. RESULTS: Dependent and avoidant personality significantly were related smartphone addiction and loneliness. Finding in structural equation modeling indicated that the loneliness partially mediated the relationship between dependent personality and smartphone addiction, but did not mediated the relationship between avoidant personality and smartphone addiction. CONCLUSIONS: This study confirmed partial mediation effect of loneliness on the relationship between smartphone addiction and dependent personality. This finding suggests that future intervention for smartphone addiction should focus on reducing of loneliness and proper coping with loneliness.

Objective To explore the relationship between avoidant personality disorder and trait coping style,especially the mediating effect of positive mental characters. Methods A sample of 8 500 male recruits was assessed with personality diagnostic questionnaire?4+( PDQ?4+) , positive mental characters scale for recruits(PMCS?R) and trait coping style questionnaire(TCSQ). Results The scores of avoidant personality disorder group were lower than control group on wisdom((3.41±0.77) vs (3.76±0.74)),courage ((3.62±0.76) vs (4.05±0.78)),humanity((3.59±0.75) vs (3.98±0.72)),justice((3.64±0.75) vs (4.02 ±0.76)),temperance((3.58±0.85) vs (4.01±0.83)),transcendence((3.77±0.72) vs (4.13±0.71)),posi?tive mental characters((3.60±0.66) vs (3.99±0.62)) and trait coping style((32.74±6.71) vs (36.61± 6.23)),while negative coping style score was higher than control group((30.87±6.91) vs (22.79±6.96)) respectively,with statistical significance( all P<0.01) . Avoidant personality disorder had significantly negative correlation with positive mental characters and trait coping style( r=-0.323,-0.320,all P<0.01) ,and signif?icantly positive correlation with negative coping style ( r=0.579, P<0.01). Positive mental characters had significantly positive correlation with trait coping style( r=0.548, P<0.01) ,and significantly negative corre? lation with negative coping style( r=-0.289, P<0.01). Hierarchy regression analysis showed that positive mental characters mediate the relationship between trait coping style ( positive coping style,negative coping style) and avoidant personality disorder ( the value of mediating effect was 50.07%,6.36%) . Conclusion ?Recruits’ avoidant personality disorder affects trait coping style not only directly,but also indirectly through positive mental characters.
