Worksheet 2: Summary of the Self-Report Method
Outline key features of the self-report method
Identify ethical issues related to the self-report method
Outline strengths of the self-report method
Outline weaknesses of the self-report method
KEY FEATURES: Self-Report
Self-report is a method of data collection in which the participant
themselves answer questions about their behaviour, thoughts and
feelings. Questions may be asked in an interview or in the form of a
questionnaire that participants are asked to respond to.
 Instead of using an objective method of data collection, participants are asked to make
subjective judgements.
Interviews are ac commonly used technique in clinical psychology and psychotherapy.
They can be structured, semi structured or unstructured.
Usually self-report questions are responded to by participants themselves, although
occasionally others respond for them e.g. In the case of small children or people with
learning difficulties who are unable to respond on their own behalf.
The most common form of self-report in psychological investigations is the
questionnaire or psychological measure.
As with observations, self-report is a method in its own right, but it is also frequently
incorporated into experiments

Method of Self Report:
QUESTIONNAIRES
KEY FEATURES: Questionnaires
Questionnaires and psychological tests such as personality test and IQ
tests are all self-report measures.
Questions in a questionnaire can be open or closed.
Open questions area open ended and allow free rein in answering
them.
Closed questions have a limited number of possible responses. They
can be questions that require a simple yes/no answer or they require an
answer from a range of possible answers.
Questionnaires frequently use rating scale. They can consist of
questions ore statements that participants respond to on a scale (e.g.
Likert scale) where responses may take the form of ‘strongly disagree’
to ‘strongly agree’ on a scale of 1-4 where 1=strong disagree and
4=strongly agree.
If participants have to select answers from a range of possible
responses they can be referred to as forced-choice questions.
OVERVIEW: Questionnaires
Nature & Use
Set of questions
Design: open (qual) or closed (quan)
Advantages
•A lot of data can be collected
•Does not require specialist administrators
•People are more willing to answer embarrassing
or personal questions on an anonymous written
questionnaire than in a face-to-face interview
Disadvantages
•Leading questions, social desirability bias
•Biased samples
Ethical Issues
Confidentiality
Privacy
Method of Self Report:
INTERVIEW
KEY FEATURES: Interviews
Unstructured - Structured - Semi Structured
a.
Unstructured interview
In an unstructured interview there is no predetermined structure in the
interview, although the interviewer will normally have some goal or sense of
direction in mind. The interviewer will ask open-ended questions and the
answers given by the interviewee stimulate new questions. The directed but
unstructured interview is the type of interview normally used in a therapeutic
context as a therapist’s aim will enable the patient to talk.
b.
Structured interview
In a structured interview the interviewer has a predetermined list of questions
which they stick to. Respondents are all asked the same questions in the same
order.
c.
Semi-Structured interview
In a semi-structured interview the interviewer has a list of questions but the
approach is flexible and can be shaped by the interviewee’s responses.
OVERVIEW: Interviews
Nature & Use
Questions can be predetermined, or created
in response to answers.
Design: structured/ unstructured questions
Advantages
•Lots of ‘rich’ data
•Telephone interviews
Disadvantages •Social desirability bias, interview bias
•Requires skilled personnel
Ethical Issues
Confidentiality
Privacy
EVALUATION:
Different types of self-report methods
Strengths
Weaknesses
Unstructured
Interview
Allows collection of rich,
qualitative data
Hard to compare
responses
Structured/
Semi-Structured
interview
Enable comparisons between
participants responses
Limit interviewees
responses, so full
information is not gained.
Open ended
questions
Enable freedom to answer as
they choose
Makes statistical analysis
difficult
Close questions
Enable collection of
quantitative data and
therefore make statistical
analysis possible
Limit interviewees
responses, so full
information is not gained.
EVALUATION: Self-Reports
STRENGTHS
•Valuable method of investigating thoughts and feelings.
•Practical research method that enables collection of
large amount of data.
•Measures are usually standardised and can be
reproduced
•Can produce numerical data that can easily be analysed
•Self report is subjective and lacks scientific rigour
•Interviewing can be time consuming and not usually
conducted on large samples
WEAKNESSES •It is not possible to gauge whether respondents are
telling the truth in their responses.
•Requires respondents to recall events or feelings, which
effects reliability.

What the researcher is going to do step by step.
If it’s an observational method- what behaviour is going to be observed?
Have you classified the behaviour and created a coding system? Have all
the observers been chosen and given training on what behaviour to
observe and record? How you chosen where the observation in going to
be?
Don’t forget your key terms- i.e. what type of experiment is it? - The
strengths and weaknesses of that experiment type? Sampling methodstrengths and weaknesses of your sampling method and anything which
might affect your sample (Cohort effect). Single Blind/Double Blind
procedure? Any type of control method such as counterbalancing for
repeated measures design? What type of design in it? Inter rater
reliability? Ecological Validity? Ability to generalise?
How about any ethical issues which might need to be considered for the
study? How might they affect the results? How might you deal with
them? (Remember-brief/debriefing for a laboratory experiment?)
Remember- relate all these to the experiment in question. Responses
need to be in context. If the experiment is a laboratory experimentinclude factors that affect laboratory experiments such as low Ecological
validity which means it’s difficult to generalise outside a lab setting.
