Depression (Shapiro Ch. 14) Flashcards
What does emotion encompass in depression?
Depression includes both the presence of negative feelings and the absence of positive feelings, with sadness common in teens and irritability common in younger children.
What physiological characteristics does depression have?
Depression can involve either lethargy or agitation, insomnia or excessive sleeping, and overeating or loss of appetite.
What cognitive characteristics does depression have?
Depressive cognition is marked by negative distortions of the self, world, and future, and by causal attributions that result in low self-esteem and hopelessness
What behavioral characteristics does depression have?
Depressive behavior is usually marked by low energy, apathy, and withdrawal, although agitated behavior may also occur
What neurobiological characteristics does depression have?
*Depression is associated with low levels of serotonin activity at the synapses of neurons that regulate mood, activity, motivation, and response to reward due to inefficient transport and abnormal functioning of serotonin receptors.
*Selective serotonin reuptake inhibitors (SSRIs) block the reuptake of serotonin at synapses, resulting in its accumulation and more frequent firing of adjacent neurons
*Depression is associated with reduced size and functioning of the hippocampus, which regulates the hypothalamic pituitary-adrenal axis. This results in chronic elevation of cortisol, a stress hormone.
*Depression is associated with low levels of left prefrontal cortex activity. Both infants of depressed mothers and depressed adolescents show low activity in this “reward circuitry”
What behavioral characteristics does depression have?
*Depressed behavior is usually characterized by a low overall rate of activity, although there are bursts of agitation or mania in some forms.
*The operant perspective provides a simple explanation: Depressed people receive a low rate of positive reinforcement, which suppresses their behavior in a general way. *Several factors contribute to the low rates of positive reinforcement and activity characteristic of depression: Low energy (partly resulting from sleep disturbance), Avoidance of challenging activities, Pessimism and hopelessness about activities, Weak social skills, including depressed mood itself, which lead to rejection
What cognitive characteristics does depression have?
*Depressed people interpret events in pessimistic and self-critical ways.
*They underestimate their competence.
*In lab experiments, they selectively attend to negative stimuli and have better memory for negative than positive content, while nondepressed people show the opposite pattern.
*Depressed people focus more on negative elements of situations while focusing less on encouraging elements, compared to nondepressed people, who exhibit the opposite pattern.
*Depressed mood causes depressed cognition, as well as the other way around
How do people with depression view successes and failures?
Failures: attributed to internal reasons
Success: attributed to external reasons
How do people with depression attribute events?
NONdepressed people make attributions to small, specific causes (e.g., being weak in algebra), whereas depressed individuals make attributions to large, global causes (e.g., being unintelligent).
How might depression present in children?
It can oftentimes present as irritability
How may some youth (esp. boys) prefer to describe their depression?
bored, down, blue, bummed out
How might behavioral activation (CBT) be used with a client that is dealing with depression?
This CBT technique directly addresses the low activity level characteristic of depression.
Pleasant event scheduling: means identifying activities the client finds enjoyable (no matter how small or ordinary) and purposefully scheduling them for her.
How can therapists test depressive beliefs with evidence?
*Counselors can support the development of adaptive cognition by: Identifying “facts” that are actually beliefs (e.g., “I’m a loser”), asking about and expanding on exceptions and doubts about the complete truth of the belief, citing evidence inconsistent with the depressogenic belief, suggesting alternative explanations of facts from which the client draws depressing implications
How can reattribution be used with clients dealing with depression?
changing attributions for negative events from global, stable factors to specific, unstable factors (i.e., “That test went badly, but others haven’t, and the next ones might not)
Characterological self-blame
(attribution to a personal trait) is always dysfunctional.
