One of the most common concerns of patients who suffer from multiple sclerosis (MS) is to delay the beginning of the secondary progressive phase. Psychological factors play a role in the exacerbation or recurrence of symptoms of the disease. The current study aimed to explore the psychological antecedent factors of the transition to secondary progressive MS.

In this qualitative study, 13 participants who were suffering from secondary progressive MS selected by the convenience sampling method in Sina hospital, Tehran, Iran. The current study was conducted based on a thematic analysis approach. Data were collected using a semi-structured interview.

The main theme, "Fundamental Mechanisms", which were included two sub-themes, "Core Beliefs" and "Personality Traits" and 10 concepts. Fundamental mechanisms are an abstract concept and this theme can bring the categories together to explain the whole results. Core beliefs sub-theme was included believe in being worthless and unlovable, believe in chance and fate, believe in a dangerous world, believe in being helpless, and self-sacrifice schema. Besides, the personality traits sub-theme was included self-devaluation, dependent personality, narcissistic personality, impulsivity, and intolerance of ambiguity.

Outcomes revealed antecedent factors of the transition to secondary progressive MS is based on core beliefs. Furthermore, personality traits are complex, inclusive, and multi-dimensional factors.

The purpose of this study was to evaluate the psychological factors affecting the delay in progress of multiple sclerosis. The present study was a qualitative research with content analysis approach. The statistical population of this study was all secondary progressive multiple sclerosis patients referred to MS clinic in Sina Hospital and they had been enter to progressive phase with delay. Sampling was initially purposeful and then continued theoretically and the final sample reached thirteen individuals after theoretical saturation. Structured interviews and semi structured interviews with open-ended questions were selected as the data collection method. Data were analyzed through coding the interviews and qualitative content analysis. The analysis of the data led to the production of the main themes of Assistance Mechanisms that it consisted of three main categories of Effective Coping Style, Perceived Social Support, and Hardiness and Resilience, and seven subcategories derived from these main categories. The findings of this study showed that some psychological factors in the course of multiple sclerosis can play a protective and auxiliary role for affected persons and delay the inevitable entry into the secondary progressive phase, reduce the rate of disease progression, and prevent recurrent attacks.

Although infertility is categorized as a physiological disorder at the first level but its experience has a huge psychological and social aspect. The present study aims at determining the predictive power of cognitive representation of illness, personality and the cause of infertility in the psychological wellbeing in infertile women.Methods and Materials: 60 infertile women referred to Tehran Women General Hospital were selected by purposeful sampling method. The subjects filled out the Demographic and medical questionnaire, Illness Perception Questionnaire- Revised (IPQ-R), Type D Scale (DS14), Flourishing scale and Scale of Positive and Negative Experience (SPANE). For statistical analysis of research data, stepwise multivariate regression analysis was used.

Results obtained from stepwise regression analysis indicated that among the studied variables of the research, timeline (acute/chronic), consequences and social inhibition have more predictive power in explaining flourishing variance and could explain flourishing by 47%. Timeline (acute/chronic) and identity have more predictive power in explaining positive experience variance and could explain positive experience by 37% and negative affectivity has more predictive power in explaining negative experience variance and could explain negative experience by 14%.

The findings of the study show that flourishing has a negative meaningful relationship with timeline (acute/chronic), consequences and social inhibition; positive experience has a negative meaningful relationship with Timeline (acute/chronic) and identity and negative experience has a positive meaningful relationship with negative affectivity. Hence, programming for cognitive and emotional interventions is assumed necessary in clinical interventions for infertility.

The present study aimed to examine the role of psychological factors in explaining weight loss success in obese women. This correlative study was conducted on all obese women with BMI more than 30 who had referred to nutrition counseling center in Karaj city. Therefore, 130 obese women were selected by available sampling method. Weight of subjects on arrival and two months later was measured at therapy sessions. Also along with the first measurement, the data related to weight efficacy of lifestyle, perceived social support, personality characteristics, depression and body image, and along with the second measurement the data with the adherence scale were obtained. Stepwise multiple regression analysis was used to analyze the data. It was revealed that among all study variables, adherence, depression, agreeableness, and extroversion were predicted more significant in weight loss success and totally they could demonstrate 59% of success variance in weight loss. Based on the results, obese women with high adherence, extraversion, agreeableness and low depression, are more successful in losing weight.

Obesity is one of the health threatening problems and the second preventable mortality factor, the prevalence of which is increasing. The most frequent consequence of obesity treatment among adults is weight regain; so, preventing gradual weight regain should be the first goal in this case. The present study aims at determining the predictive power of biological, psychological and social factors in maintaining weight in the overweight and the obese. Therefore, 157 obese women referred to Sina Hospital Obesity Clinic were selected by purposeful sampling method. The subjects filled out the self-report questionnaires at the beginning of the study. Then, they underwent diet and sport medicine interventions. At the end of the sixth month, weight of the subjects was measured and the weight loss was studied. Results obtained from stepwise regression analysis indicated that among the studied variables of the research, subjective weight (SW), weight cycling, state and trait anxiety, body areas satisfaction (BAS) and appearance evaluation (AE) have more predictive power in explaining weight maintenance variance and could explain successful weight maintenance by 37%. The findings of the study show that weight maintenance has a positive meaningful relationship with subjective weight (SW), weight cycling, state anxiety and body areas satisfaction (BAS); also, there is a meaningful negative relationship with the said variable and trait anxiety and appearance evaluation (AE). Hence, programming for cognitive and emotional interventions is assumed necessary in clinical interventions for obesity.
