26
What is incidence?

39
How are people generally treated?
-many people treated by family physicians -Vast majority of treatment is done on outpatient basis
40
For what matters does inpatient hospitalisation usually happen?
Typically in psychiatric units
41
Why won't some people seek treatment?
-denial -stigma -gaslighting -so distressed that going through the process is overwhelming
42
How are inpatients treated?
-different mental health professionals work as a team -intense treatment (more rapid recovery)
43
In what cases will you be an inpatient?
-if there is significant impairment -facilitates treatment because better controlled
44
How are outpatients treated?
-smaller team -psychiatrist, psychologist, specialised counsellor.
45
What are the benefits of research?
Learn about disorders -symptoms -prevalence -duration (acute, chronic) -accompanying problems Understand etiology (causes) and nature of disorder Discover how to provide the best patient care
46
In what case is a disorder acute or chronic?
-acute: short in duration -chronic: long in duration
47
What is the etiology of a disorder ?
the causes of a disorder
48
What is the main source of information of scientist ?
Case studies
49
What are case studies?
Detailed accounts of individual patient behavior, based on observation.
50
What are disadvantages of case studies?
-subject to bias, writer decides what to include and omit -conclusions have low generalisability (can't be used to draw conclusions about other cases)
51
What does it mean that conclusions of case studies have low generalisability ?
can't be used to draw conclusions about other cases
52
What are advantages of case studies?
-Can provide insights into unusual/rare clinical conditions -Can serve as a stimulus for research

Why may self-report data be inaccurate?
-people can lie -misunderstand the question -want to present themselves in a certain way
54
How can we make sure that a self-report is as accurate as possible?

62
What is internal validity?
Extend to which a study is methodologically sound
63
What is a criterion group?
People with the condition being studied
64

65
What is a correlational research ?
-Studying the world as it is -Does not involve any manipulation of variables -Examining naturalistic relations among two or more variables (eg, depression and self-esteem)
66
What is a positive correlation ?
Two measures vary together in a direct, corresponding manner
67
What is a negative correlation?

68
What is statistical significance?
Probability that the correlation would occur purely by chance
69
What influences statistical significance?

70
What is effect size?
reflects the size of the association between two variables independent of the sample size
71
What does effect size 0 mean?
There is no association between variables
72
What does effect sizes of .20, .50 and .80 mean?

74
What is the relationship between correlational and causality?
Correlation does not mean causation (third variable problem)
75
What can't correlational studies do and what can they do?
-CAN'T prove causal relationships -CAN pinpoint questions for further research
76
What is retrospective research?
involve looking back in time: how the patients were earlier and what wet wrong
77
What is prospective research ?
looking ahead in time: identify high-risk individuals and focus on them before any disorder manifests
78
What is a longitudinal study?
a study that follows a group of people over time
79
What is experimental research ?
Allows researchers to draw conclusions about causality and resolve questions of directionality.
80
In what case is a dependent variable regarded as the cause of the outcome?
If dependent variable changes as independent variable changes, it is regarded as a cause of the outcome.
81
What is a quasi-experimental research design?
Either expose to success experience or failure experiences.
82
How is treatment research executed?
Proposed treatment is given to a designated group of patients and withheld from a similar group of patients
83
In a treatment research how do we choose who gets the treatment and who doesn't?
random assignment
84
What is a standard treatment comparison study?
alternative in which two (or more) treatments are compared in differing yet comparable groups.
85
What is a double blind study ?
Neither the subjects nor the experimenters know who is in the control group.
86
What is a placebo treatment?
Participants are given a treatment with no effect
