Fulltext Comparative study on attitudes and psychological problems of mothers towards their children with developmental disability

Shobana M, Saravanan C

East Asian Arch Psychiatry, 2014 Mar;24(1):16-22.
PMID: 24676483

Objective: Parents’ positive attitudes and psychological wellbeing play an important role in the development of the children with developmental disability. This study aimed to measure the prevalence of psychological problems among mothers of children with autism disorder, intellectual disability, and Down syndrome. The second aim was to assess the differences in mothers’ attitudes and psychological problems among their children with intellectual disability, autism disorder, and Down syndrome. The third aim was to identify whether negative attitude was a predictor of psychological problems in these mothers.
Methods: In this study, 112 mothers of children having mild and moderate levels of autism disorder, Down syndrome, and intellectual disability were assessed using the Parental Attitude Scale and General Health Questionnaire–28.
Results: Overall, mothers of children with intellectual disability were found to have the most negative attitude towards their child. Mothers of children with autism disorder exhibited higher scores on somatic symptoms, anxiety, and social dysfunction when compared with their counterparts with Down syndrome and intellectual disability. Negative attitude was a significant predictor of psychological problems.
Conclusion: Parental attitudes and psychological problems would vary among mothers of children with different types of developmental disability.

Fulltext Psychological problems and psychosocial predictors of cigarette smoking behavior among undergraduate students in Malaysia

Saravanan C, Heidhy I

Asian Pac J Cancer Prev, 2014;15(18):7629-34.
PMID: 25292039

BACKGROUND: Cigarette smokers have their own motivation and justification to smoke. For example, smoking reduces their stress or enhances their pleasure. This study aimed to identify the (a) prevalence of cigarette smokers among undergraduates in Malaysia, (b) gender differences in nicotine dependence among current smokers, (c) differences in psychological problems (depression, anxiety and stress) based on the status of smoking cigarettes (current, former and non-smokers) and (d) extent to which precipitating factors (tension reduction, addiction, automatism, handling, social interaction, pleasure, and stimulation) predict the smoking behavior among current smokers.

MATERIALS AND METHODS: In this study 780 undergraduate students participated from a private university in Kuala Lumpur and Selangor state in Malaysia. The Depression, Stress and Anxiety Scale, Modified Reason for Smoking Scale and Fagerstrom Nicotine Dependence Test were used to measure psychological problems, predictors of smoking behavior and nicotine dependency among current smokers.

RESULTS: The results showed that 14.7%(n=106) of the students were smokers. Current smokers exhibited more psychological problems (depression, anxiety and stress) compared to former and non-smokers. Addiction, tension reduction, pleasure and automatism were predictors of smoking behavior among the current smoking students. Step wise regression analysis showed that smoking behavior was highly predicted by nicotine dependency or addiction. Smoking students were motivated to smoke cigarettes as they believed that it reduced their tension and enhance pleasure.

CONCLUSIONS: Hence, there is a need for health promotion and anti-tobacco prevention as cigarette smokers experience more psychological problems. Nicotine dependency or addition was one of the major causes for smoking behavior among the student population in Malaysia.

PMID: 24688425 DOI: 10.1155/2014/737382

Medical school is recognized as a stressful environment that often has a negative effect on students' academic performance, physical health, and psychosocial well-being. Previous studies have not identified differences between depressed and nondepressed and anxious and nonanxious medical students' experiences of stress or their reactions to stressors. The present study aimed to identify the prevalence of depression and anxiety among a sample of 358 medical students attending a private university in Malaysia and to examine differences according to participants' gender, year of study, and stage of training (preclinical and clinical). Additionally, this study examined the extent to which stress predicts depression and anxiety, differences between depressed and nondepressed medical students' experiences of and reactions to stressors, and differences between anxious and nonanxious medical students' experiences of and reactions to stressors.

Saravanan C, Kingston R

J Res Med Sci, 2014 May;19(5):391-7.
PMID: 25097619

BACKGROUND: Test anxiety aggravates psychological distress and reduces the motivation among graduate students. This study aimed to identify psychological intervention for test anxiety, which reduces the level of psychological distress, amotivation and increases the intrinsic and extrinsic motivation among medical students.
MATERIALS AND METHODS: Westside test anxiety scale, Kessler Perceived Stress Scale and Academic Motivation Scale were used to measure test anxiety, psychological distress and motivation on 436 1(st) year medical students. Out of 436 students, 74 students who exhibited moderate to high test anxiety were randomly divided into either experimental or waiting list group. In this true randomized experimental study, 32 participants from the intervention group received five sessions of psychological intervention consist of psychoeducation, relaxation therapy and systematic desensitization. Thirty-three students from waiting list received one session of advice and suggestions.
RESULTS: After received psychological intervention participants from the intervention group experienced less anxiety, psychological distress, and amotivation (P < 0.01) and high intrinsic and extrinsic motivation (P < 0.01) in the postassessment compared with their preassessment scores.
CONCLUSION: Overall psychological intervention is effective to reduce anxiety scores and its related variables.

Fulltext The prevalence and inter-relationship of negative body image perception, depression and susceptibility to eating disorders among female medical undergraduate students

Manaf NA, Saravanan C, Zuhrah B

J Clin Diagn Res, 2016 Mar;10(3):VC01-VC04.
PMID: 27134977 DOI: 10.7860/JCDR/2016/16678.7341

Introduction: Female students are thought to be more negatively impacted by body image ideals and often more susceptible to various eating related disorders compared to men. A previous study using a sample of female students in Malaysia did not identify whether the increase in susceptibility to eating disorders can be explained by the level of body image acceptance.
Aim: To identify the prevalence of depression and susceptibility to eating disorders among a sample of 206 female students in one of the private universities in Malaysia and explore the relationship between depression, body image and susceptibility to eating disorders. In addition, this study aimed to determine whether depression is a mediator between body image and susceptibility to eating disorders among female college students.
Materials and Methods: The Body Image Acceptance and Action Questionnaire were used to assess body image acceptance, the Patient Health Questionnaire to measure depression and the Eating Attitude Test- 26 was used to assess susceptibility to eating disorders.
Results: The results showed that 65.5% (n=135) of the students were depressed and 6.3% (n=13) were susceptible to eating disorders. There was a significant positive relationship between depression and eating disorders and a negative relationship between body image and depression as well as between body image and eating disorder. Further, the regression model showed that depression was partially mediating the effect of body image on eating disorders.
Conclusion: Body image and depression contribute to eating disorders and treating depression could reduce susceptibility to eating disorders.

The effects of brief individual cognitive behavioural therapy for depression and homesickness among international students in Malaysia

Saravanan C, Alias A, Mohamad M

J Affect Disord, 2017 10 01;220:108-116.
PMID: 28618312 DOI: 10.1016/j.jad.2017.05.037

BACKGROUND: Students who go to other countries for higher education face various psychological problems, particularly homesickness and depression. The objectives of this study were to: (a) identify differences between students who did and did not receive brief individual cognitive behavioural therapy (CBT) for depression to reduce homesickness; (b) identify whether brief individual CBT for depression reduces the level of homesickness in students between pre-, post- and follow-up assessment; and (c) compare the scores of students experiencing only homesickness and those experiencing both homesickness and depression.
METHOD: The sample consisted of 520 first-year undergraduate international students. The experimental group contained students who were diagnosed with depression and homesickness and received seven sessions of brief individual CBT for depression to reduce homesickness. The control group contained students who were diagnosed with depression and homesickness and received one session of advice and suggestions. The comparison group contained students who experienced only homesickness and did not receive any interventions. The study used the comparison group to determine if an interaction effect existed between students experiencing only homesickness and students experiencing both homesickness and depression.
RESULTS: Students who received brief individual CBT displayed a significant reduction in their homesickness and depression scores compared to the scores of students in the control group. Students who experienced only homesickness exhibited a significant reduction in the scores on homesickness in the post-assessment compared to the control group's post-assessment homesickness scores.
LIMITATION: The results of this study cannot be generalized as data were collected from three universities in Malaysia. The follow-up assessment was conducted six months after the post-assessment, which also limits generalizability beyond six months.
CONCLUSION: Overall, homesickness is considered a normal reaction. Brief individual CBT for depression is effective in reducing homesickness and depression among international students.

PMID: 30895272

Background: Dental anxiety is a common problem associated with poorer oral health. Managing anxiety is key to improving oral health of patients with dental anxiety. The present pilot study therefore investigated dental anxiety prevalence among patients visiting a university dental clinic. We further examined the effect of combined psychological interventions on anxiety or concern towards dental treatment procedures before treatment, after treatment, and at follow-up.
Methods: In this prospective pilot study, patients seeking restorative treatment were screened for dental anxiety and dental concern about treatment using the Dental Anxiety Scale-Revised (DAS-R) and Dental Concern Assessment (DCA) questionnaires. Participants with a DAS-R score of 9 or above were randomly assigned to an experimental or control group. The patients in the experimental group received two psycho-logical interventions (psychoeducation and progressive muscular relaxation) prior to dental treatment. Dur-ing treatment, patients received another psychological intervention (music distraction). No psychological interventions were given to control patients. DAS-R and DCA scores were used to assess dental anxiety and concern, respectively, before treatment, after treatment, and at follow-up. Nonparametric tests were used for intergroup and intragroup statistical analyses.
Results: Out of 64 patients surveyed, 33 (51.6%) had experienced dental anxiety. Of those, 2 were exclud-ed, and 31 patients with a mean ± SD age of 41.2 ± 15.9 y completed the study. No intergroup differences in dental anxiety were found in terms of pretreatment, posttreatment, and follow-up treatment. The mean rank value of the dental anxiety score was less in the experimental group (13.53) than the control group (18.31), albeit not significant. More specifically, differences (Kruskal-Wallis %2 = 14.82, P = 0.001, effect size = 0.33) were found in the experimental group for pretreatment, posttreatment, and follow-up treatment levels of dental anxiety for extraction (P = 0.01), injection (P = 0.02), and sound/vibration of the drill (P = 0.00). No significant intragroup differences between pretreatment, posttreatment, and follow-up treatment were found in the control group.
Conclusions: The combined brief psychological interventions reduced dental anxiety.
Relevance for patients: The psychological interventions of the present study could be applied right before or during dental treatment to reduce the dental anxiety of patients. However, additional research involving larger groups is needed to replicate the results of this pilot study.
Salivaomics in head and neck cancer

Saravanan C, S M N Mydin RB, Mohamed Sheriff NR, Kaur G, Singh Dhaliwal S, Musa MY

Clin Chim Acta, 2025 Jan 15;565:119952.

Salivaomics is a promising method for the early detection and monitoring of head and neck cancer (HNC). By analyzing salivary proteomics, RNA, and DNA, it identifies biomarkers that distinguish HNC patients from healthy individuals. Saliva's non-invasive, easily collectible nature and affordability make it an advantageous screening tool. Multiomics approaches, which explore genetic mutations, gene expression patterns, protein profiles, and metabolite levels, provide a comprehensive molecular perspective that enhances clinical applicability. The approaches enhance the precision of diagnoses, enable the development and application of targeted therapies, and contribute to the overall advancement of personalized medicine. Despite its potential, larger-scale studies are essential for validating biomarkers, and assessing sensitivity, accuracy, and specificity in detecting HNC. This review highlights salivaomics' potential as a non-invasive, accessible biological sample for early disease detection in HNC and underscores the value of multiomics in advancing this research. Salivaomics offers significant insights into the underlying mechanisms of HNC, enabling the discovery of robust, non-invasive biomarkers for improved disease management.
