Description of intervention(s) / exposure
This is a longitudinal study based on questionnaire data. Multiple somatic symptoms are determined via the Patient Health Questionnaire - 15 (PHQ-15). Those who score high on the PHQ-15 experience a collection of symptoms such as back pain, stomach ache, dizziness and headache. Over a 1 year period, these symptoms will be correlated with co-morbid diseases and psychological health, in order to a) determine the stability of these symptoms and b) its temporal relationship with co-morbid diseases and psychological health.

Outcomes
Primary outcome [1] 306032 0
Multiple Somatic symptom (Patient Health Questionnaire - 15). Symptom severity cut-offs;
0 - 9 = mild, 9 - 14 = moderate, 15 - 30 = severe. Determine the numbers of participants with multiple somatic symptoms

Baseline and 1 year follow-up
Secondary outcome [1] 347387 0
Whitely Scale for hypochondriasis - 7. Higher scores reflect increased health anxiety. Change in hypochondriasis and identify temporal relationships with multiple somatic symptoms.

Secondary outcome [2] 347388 0
Patient Health Questionnaire - 4. Higher scores reflect increased anxiety and depressive symptoms. Change in anxiety and depression. Change in anxiety and depression, and identify temporal relationships with multiple somatic symptoms.

Baseline and 1 year follow up
Secondary outcome [3] 347389 0
Cognitive Emotion Regulation Questionnaire - (Catastrophising sub scale ). Higher scores reflect symptom catastrophising. Change in catastrophising, and identify temporal relationships with multiple somatic symptoms.

Baseline and 1 year follow up
Secondary outcome [4] 347390 0
Co-morbid chronic diseases. Total score represents increased medical co-morbidity. This was designed specifically for the study. A checklist of common chronic disorders is presented, in addition to a space for participants to indicate any other chronic diseases they have been diagnosed with.

Statistical methods / analysis
1. Descriptive analyses: all measures will be reported descriptively. Numeric measures
will be reported as mean and standard deviation while qualitative measures will be
reported as count and percentage. The prevalence of individual with clinical rates of
low, moderate or high MSS will be reported along with 95% confidence intervals.
2. Cross-sectional analyses: Common connections between MSS with respect to
psychosocial factors will be understood through multivariate modelling.
3. Longitudinal analyses will be undertaken for two purposes. The first is to understand
the stability of individual MSS and also whether there is substitution between MSS which is possible given their reported comorbidity. The second is to understand whether psychological state at baseline predicts MSS state at follow-up. In doing so we will study mind-body and body-mind axes to determine whether a reciprocal relationship exists for MSS.
