Figure 1.2 The Burden of Mental Illness for Different Disorders Across the Lifespan Disability adjusted life years (DALYs) for various mental and substance use disorders are shown according to age. DALYs represent the total (worldwide) number of otherwise healthy years of life that are lost or profoundly impacted because of the disorder. Depression causes the greatest total disability. This is because depression is a relatively common disorder. (Adapted from Whiteford et al., 2013. Global burden of disease attributable to mental and substance use disorders: findings from the Global Burden of Disease Study 2010. Lancet, 382, 1580.) Copyright © 2017 Pearson Education, Ltd.

With less than 400 psychiatric doctors, Hong Kong has half the number recommended by the World Health Organisation for our population size. From 2011/12 to 2015/16, the number of Hospital Authority psychiatric patients increased by 22%, but psychiatric staff increased only 13%, with the number of psychiatrists in particular increasing only 3% and psychiatric hospital bed count remaining unchanged. Currently, there is a total number of 25,671 registered social workers , 603 clinical psychologists registered under Hong Kong Psychological Society, and a total of 422 psychiatrists including both public and private sector registered under the Medical Council of Hong Kong. Patients’ wait time to see a psychiatrist can be up to almost 2 years, and each appointment lasts on average only 6-8 minutes. 60% of Hong Kong adults do not know where to seek help regarding mental health outside of hospitals. Low-income families are often unable to afford unsubsidised health as the cost of private sector psychiatric consultations ranges from $790 to $3,000. Copyright © 2017 Pearson Education, Ltd.

Psychological Approaches (i) The psychodynamic model, – (a) Symptoms are rooted in unconscious conflict (between the id and superego). – (b) Defense mechanisms (e.g., repression, denial) are reflexively or unconsciously employed to avoid pain caused by conflicting motives and anxieties. (ii) Behavioral theorists describe abnormal behaviors as being acquired in the same manner as normal behaviors, through learning (e.g., reinforcement). – (a) Symptoms and maladaptive behavior may be maintained by current conditions and reinforcers. – (b) Both classical and operant conditioning models are used to understand the processes that can result in maladaptive behavior. (iii) Cognitive perspectives often refine behaviorist views. – (a) It is important to consider how the individual perceives himself, or sees one’s relations with others and the environment. – (b) Problems result from distortions in perceptions of the reality of a situation. (iv) The sociocultural perspective emphasizes the role culture plays in both the etiology and the diagnosis or labeling of abnormal behavior. Copyright © 2017 Pearson Education, Ltd.
