Psychological Problems Flashcards
What are the incidence rates of mental health problems?
MIND – Incidence rates per 100 people:
Anxiety: 4.7
Depression: 2.6
Eating disorders: 1.6
1 in 2 people will experience mental health problems.
How have the incidences of mental health problems changed over time?
In 2007 24% of adults were accessing treatment.
Rising to 37% in 2014.
It’s estimated that by 2030 two million more adults will have mental health problems than in 2013.
More women are treated than men and the gap is widening.
What are the theories as to why mental health incidence have increased over time?
Increased challenges of modern living
Lessening of social stigma
Increased recognition of the nature of mental health problems
What are the cultural variations in beliefs about mental health problems?
In Western society hearing voices is a symptom of mental health problems such as schizophrenia, but it is a positive experience in India and Africa.
Some syndromes are culture-bound, occurring only in certain cultures, e.g. eating disorders were relatively rare for many years outside the Western world.
What are individual effects?
The way that mental health problems affect the person experiencing them.
What are the individual effects of mental health problems?
Damage to relationships
Difficulties coping with day-to-day life
Negative impact on physical well-being
What are social effects?
The way that mental health problems affect others in society.
What are the social effects of mental illness?
Need for more social care
Increased crime rates
Implications for the economy
What is clinical depression?
Clinical depression is the name for depression as a medical condition.
How are sadness and depression different?
Sadness is a ‘normal’ emotion where you can still function.
Depression involves an enduring and all-encompassing sadness that stops the ability to function.
What is unipolar depression?
One emotional state (depression).
What is bipolar depression?
Depression alternates with mania, and also periods of normal mood.
Mania is an exaggerated state of intense well-being.
What is the ICD?
Mental health problems are diagnosed in the same way as physical illnesses. Symptoms are agreed by professionals.
The International Classification of Diseases (ICD-10) lists symptoms of different disorders and a person is diagnosed with any one disorder if they display the symptoms.
What is necessary for a diagnosis of depression?
A diagnosis of mild unipolar depression requires two of the three key symptoms plus two others.
Moderate requires five or six symptoms and severe requires seven or more.
Symptoms should be present all or most of the time, and for longer than two weeks.
What are the key symptoms of depression?
- Low mood: Depressed mood most of the day and nearly every day.
- Loss of interest and pleasure: Diminished interest or pleasure in most activities most of the day.
- Reduced energy levels: This has a knock-on effect on work, education and social life.
What are the other symptoms of depression?
- Changes in sleep patterns: Reduced sleep (insomnia), early waking, or more need for sleep (hypersomnia).
- Changes in appetite levels: This may increase or decrease, leading to weight gain or loss.
- Decrease in self-confidence: May have a sense of self-loathing (hating themselves).
Four further symptoms: such as guilt, pessimism, ideas of self-harm or suicide, reduced concentration.
What are neurotransmitters?
Messages travel along a neuron electrically but the message is transmitted chemically across the synapse by neurotransmitters.
Serotonin is a neurotransmitter which has been linked to several behaviours including depression.
What is serotonin?
High levels of serotonin in the synaptic cleft means the postsynaptic neuron is stimulated, improving mood.
Low levels at the synapse means less stimulation of the postsynaptic neuron, resulting in a low mood.
What are the effects of serotonin?
Serotonin also affects memory, sleep and appetite.
These are linked to the characteristics of depression, e.g. lack of concentration, disturbed sleep and reduced appetite.
What are the reasons from low serotonin levels?
Genes may cause low serotonin levels where someone inherits a poor ability to produce serotonin.
Diet (an environmental influence) may cause low levels of tryptophan, a key ingredient of serotonin. High-protein foods and carbohydrates contain tryptophan.
What are the evaluation points for the biological explanation of depression?
One strength of the biological explanation of depression is that there is supporting research evidence.
McNeal and Cimbolic found lower levels of serotonin in the brains of people with depression.
This suggests that there is a link between low levels of serotonin and depression.
One weakness of neurotransmitter explanations is low levels of serotonin could be an effect of being depressed.
Thinking sad thoughts and having difficult experiences could cause low serotonin levels.
This means low levels of serotonin may be an effect of psychological experiences rather than the cause of them.
One weakness is that depression may not be solely caused by abnormal levels of neurotransmitters.
Some people with low levels of serotonin don’t have depression and some people with depression don’t have low levels of serotonin.
This means that the neurotransmitter explanation isn’t enough on its own.
What is faulty thinking?
The cognitive approach sees depression as caused by faulty or irrational thinking.
When a person is depressed they focus on the negative and ignore positives and think in black-and-white terms.
This creates feelings of hopelessness and depression.
What are negative schemas?
Schemas are mental frameworks containing ideas and information developed through experience.
Having a negative self-schema means you are likely to interpret all information about yourself in a negative way.
What are attributions?
Attribution is the process of explaining causes of behaviour.
Seligman proposed that some people have a negative attributional style.
There are internal, stable and global attributions which result in depression.
What is learned helplessness?
Seligman suggested that a negative attributional style is learned.
An unpleasant experience makes you try to escape but if you can’t escape, you learn to give up trying. This is called ‘learned helplessness’.
What are the evaluation points for cognitive explanations of depression?
One strength is that there is research support for learned helplessness.
Seligman has demonstrated the process of learned helplessness. Dogs learned to react to challenge by ‘giving up’.
Therefore, this research supports his explanation of depression due to negative attributions.
One strength is that the cognitive explanation leads to ways of treating depression.
Cognitive behaviour therapy teaches people to think differently replacing faulty, irrational thinking with rational thinking to help relieve depression.
Therefore, the explanation leads to successful ways to help people with depression.
One weakness is that negative beliefs may simply be realistic rather than depressing.
Alloy and Abramson found that depressed people gave more accurate estimates of the likelihood of a disaster than ‘normal’ people (‘sadder but wiser’).
Therefore, a negative attributional style may not be all bad.
What is selective serotonin reuptake inhibitor?
Low levels of serotonin may cause depression, therefore increasing serotonin levels may treat depression.
SSRIs selectively target serotonin at the synapse.
SSRIs inhibit the reuptake of the serotonin molecules.
