A client is wondering about the genetic factors that contribute to depression. What is the relationship between genetic factors and depression according to the text?
Depression is solely caused by genetic factors, with no influence from environmental factors.
Genetic factors play a minor role in depression, with environmental factors being the primary cause.
Genetic theory suggests that specific genes are responsible for causing depression, independent of environmental factors.
Genetic factors make some individuals more vulnerable to developing depression, but environmental factors also play a significant role in its expression.
The Correct Answer is D
Choice A rationale:
Depression is not solely caused by genetic factors. While genetics do play a role in predisposing individuals to depression, it's a complex interplay between genetic susceptibility and environmental influences that contribute to the development of the disorder.
Choice B rationale:
Genetic factors are not minor players in depression. Research suggests that genetics can significantly influence a person's susceptibility to depression. However, environmental factors, such as trauma, stress, and life experiences, also contribute substantially to the onset and course of depression.
Choice C rationale:
The relationship between genetics and depression is not as straightforward as specific genes causing depression independently of environmental factors. Depression is a multifactorial disorder influenced by a combination of genetic, biological, psychological, and environmental factors.
Choice D rationale:
This is the correct answer. Genetic factors do contribute to an individual's vulnerability to depression. Studies of families, twins, and heritability have demonstrated a genetic component to depression. However, it's crucial to recognize that genetic predisposition interacts with environmental factors. Trauma, loss, chronic stress, and other environmental triggers can precipitate depressive episodes in genetically susceptible individuals.

Correct Answer is D
Explanation
Choice A rationale:
Signs of normal bereavement. Bereavement refers to the period of grief and mourning after the loss of a loved one. While fatigue and feelings of worthlessness can be experienced during bereavement, difficulty concentrating is not a typical sign. Additionally, bereavement-related symptoms typically improve over time as the individual processes their loss. The combination of extreme fatigue, difficulty concentrating, and thoughts of worthlessness suggests a more severe and persistent condition than normal bereavement.
Choice B rationale:
Symptoms of bipolar disorder. Bipolar disorder is characterized by alternating episodes of depression and mania (or hypomania). The client's symptoms of extreme fatigue, difficulty concentrating, and thoughts of worthlessness are primarily indicative of a depressive episode, which is only one aspect of bipolar disorder. Bipolar disorder requires the presence of manic or hypomanic episodes, which are not mentioned in the client's presentation.
Choice C rationale:
Indicators of substance-induced mood disorder. Substance-induced mood disorder occurs as a result of substance use or withdrawal and involves changes in mood and affect. While substances can lead to symptoms similar to depression, the combination of symptoms presented by the client (fatigue, difficulty concentrating, thoughts of worthlessness) is more indicative of a primary mood disorder rather than one directly caused by substance use.
Choice D rationale:
Criteria for diagnosing MDD according to DSM-5. The client's symptoms of extreme fatigue, difficulty concentrating, and thoughts of worthlessness align with the criteria for Major Depressive Disorder (MDD) as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). These criteria include the presence of specific symptoms for a specified duration, causing significant impairment in functioning. The symptoms should not be better explained by other conditions or substances. In this case, the client's presentation closely matches the criteria for diagnosing MDD.
Correct Answer is A
Explanation
Choice A rationale:
Patient Health naire (PHQ-9). The PHQ-9 is a commonly used depression assessment tool that evaluates a patient's mood and depressive symptoms. It consists of nine questions that correspond to the nine criteria for diagnosing major depressive disorder (MDD) according to the DSM-5. The tool assesses various aspects of depression, such as mood, sleep disturbances, appetite changes, and more. It's a self-report questionnaire that helps clinicians assess the severity of a patient's depression and track their progress over time.
Choice B rationale:
Hamilton Depression Rating Scale (HAM-D). The Hamilton Depression Rating Scale (HAM-D) is another widely used tool for assessing the severity of depressive symptoms in patients with mood disorders. It contains multiple items that evaluate various aspects of depression, such as mood, feelings of guilt, suicidal ideation, and more. Unlike the PHQ-9, the HAM-D is typically administered by a trained clinician and is more extensive, making it suitable for clinical research and diagnosis but potentially less practical for routine screening.
Choice C rationale:
Beck Depression Inventory (BDI). The Beck Depression Inventory (BDI) is a self-report questionnaire designed to assess the presence and severity of depressive symptoms in individuals. It consists of 21 multiple-choice questions that cover various emotional, cognitive, and physical symptoms of depression. The BDI is useful for assessing the intensity of depression and changes in symptom severity over time. While a valuable tool, it's not the assessment tool most likely used in this scenario.
Choice D rationale:
Mini-Mental State Examination (MMSE). The Mini-Mental State Examination (MMSE) is not an appropriate tool for assessing depression. Instead, it's a brief cognitive screening test used to assess cognitive impairment and cognitive decline in individuals, especially in older adults. It evaluates aspects such as orientation, memory, attention, language, and visuospatial skills. It is not designed to assess mood, anxiety, or other emotional aspects related to depression.
