3 Key Issues Sampling issues Ethical issues Reliability and validity
3 key issues
Potential for sampling bias
Ethical issues in Internet research?
Validity of the data- impact on the established psychometric properties of measures
Sampling Issues
Two approaches (open and selective)
Open (convenience sampling)
Enhance representation?
Can large samples override potential bias?
Presence and impact of self-selection can be traced to some degree
Sampling issues
Selective (if able to define population)
Few studies based on a randomly selected sample
Convenience sample random allocation
Propensity scoring an option
Response rates
Unsolicited e-mail (with electronic return) generates lowest response rate, even when compared to unsolicited postal survey.
Impact of presentation- browser type, download time, password, security issues, computer anxiety, computer self-efficacy
Ethical Issues
Seeking/obtaining consent
Protecting participants’ anonymity
Security of site
Opportunistic research
Ethical issues in planned research
Developing informed consent
Ability to ensure a level of anonymity
Security of site
Opportunistic research
When and how is material posted on the web classed as public or private?
Level of “disguise” in presenting results?
Issue of perceived privacy
Are researchers “lurkers”?
Is the process of “non-alienation” acceptable?
Reliability and validity
Equivalence must be demonstrated not assumed
Some evidence of differences in the distribution of scores and psychometric properties (e.g. factor loading)
Reliability and credibility
Layout of pages
Linguistic competence
Culturally driven interpretations
Low attentiveness
Repeat participation
Incomplete submissions
Misrepresentation of self
Construct validity
Psychometric properties
Mixed evidence
How critical are the differences?
Difficult to disentangle issues around sampling biases and possible effects of completing measures on-line.
Sampling Issues in Internet-Mediated Research Dr Judy Proudfoot
Online Psychoeducation for Bipolar Disorder: Randomised Controlled Trial

A/Prof Meg Smith – University of Western Sydney
Background
Bipolar Disorder is difficult to detect. Accurate diagnosis can take 10-20 years.
Poor treatment adherence, inadequate self management, increased levels of disability are common.
40% of patients relapse in 1 year, 60% over 2 years and 73% over 5 years (Gitlin et al, Am J Psych, 1995) .
Psycho-education reduces relapses and hospitalisations. Not previously delivered online.
Research Study
RANDOMISED CONTROLLED TRIAL
Does an 8-module online education program + ‘treatment as usual’ for Bipolar Disorder improve psycho-social adjustment in adults with newly-diagnosed BD
With and without online support from an apomediary (“informed supporter”).
In comparison with online information about bipolar disorder + monitoring.
Bipolar Disorder Education Program
Topics
Diagnosing Bipolar Disorder
Causes of Bipolar disorder
Medications
Psychological Treatments
Stay-Well Plans (identifying triggers and early warning signs, and designing preemptive actions involving pt and family)
Support Networks and Carers
Omega-3 as a treatment for depression
Person First Illness Last
Random Allocation Bipolar Disorder Education Program Email support from an apomediary + lnformation + Monitoring
Online interventions
One online module per week over 8 weeks
Workbook activities to assist participants to apply the information and strategies to their situation
Self-monitoring between sessions
“Informed Supporters”
People with bipolar disorder
Effectively managing their condition for >2 years
Trained to provide email support to participants under supervision of our clinical team.
Informed Support
At least one and maximum two emails per week sent to each participant (max 300 words per email), with invitation to respond.
Practical advice about how to set up a “well-being plan” (strategies to minimise risks and illness triggers and a contingency plan for times when unwell) as well as general issues about bipolar disorder.
Posts from Informed Supporters are checked for adherence and safety.
Posts from participants to Informed Supporters are monitored for adverse events.
Inclusion Criteria:
18+ years old
Diagnosed with BD in previous 12 months
Currently receiving regular care from psychiatrist or GP
Has access to internet and printer, and is computer literate
Able to read and write English
Living in Australia
Screening
Bipolar Disorder Assessment Test (Parker et al., 2006) Sensitivity: Specificity:
Potential for over-ride by Black Dog Institute Psychiatrists (who validated the BDAT)
Sampling
Open (convenience) sampling: - Via Internet Black Dog Institute website, websites of professional organisations, websites of mental health organisations in Australia - Via print media Newspaper advertisements and articles
Sampling (cont)
Selective Sampling:
- Via Black Dog Institute Mood Disorders Clinic – invited participation - Via leaflets at special events , eg Fun Runs, Flower Festivals, Training programs for GPs, School Counsellors
Sampling (cont)
Variety of recruitment methods to minimise sampling bias and maximise response rates.
But still not a random sample (ie each member of the population does not have equal probability of being selected).
No recruitment by unsolicited email (lower response rate).
But still low response rate (3-4 per week) - due to tight inclusion criteria?
- due to phenomenology of BD diagnosis?
A Solution?
Methodological Issues and Ethical Challenges in e-Health Research: Panel Discussion Dr Caryl Barnes MBBS,FRANZCP Doctoral fellow University of New South Wales, Sydney, Australia ‘ HealthSteps (formally Recovery Road) for Bipolar Disorder’: an on-line relapse prevention program
Overview
Bipolar disorder: role of internet in treatment
Aims of RCT: ‘ Taking control of Bipolar Disorder: Staying well, Learning more’-12 month online relapse prevention program
Ethical issues considered
Privacy/Confidentiality/Anonymity
Informed consent
Analysis of potential risk to participants/ benefits
Beneficence/ Duty-of-care
Discussion
Bipolar Disorder: role of internet in treatment
Common 1-2% of the general population
Chronic relapsing remitting illness
6th highest cause of disability world wide (WHO figures)
Frequent relapses despite good adherence to medication
Psychological interventions vital part of treatment e.g. psycho-education / CBT
Disadvantages
time consuming,
expensive
depending on area, difficult to access

Risks/Benefit Ratio
Low risk of inducing psychological distress
No risk of physical harm
Vulnerable population recognized; inclusion criteria had to be under care treating mental health professional
Program adjunctive only
Belief participation would benefit participants
Duty of Care
Need to recognize worsening/ life threatening symptoms/ suicidal ideation
Developed a RED FLAG system
Outcome measures set to trigger flag within system
Individual data entry reviewed, if required de-identification participant, review of consents
Email to participant, if applicable to treating clinician
Discussion
Restraints caused by a research collaboration-private and public entities
Privacy- not enough identifying details collected
Informed consent process – was this sufficient?
Risk/Benefit
email
Ongoing clinician contact?
Discussion
Duty of care
Management of participants outside of Australia
Red flag system appreciated-feedback received rated this most useful components of study
Consent to contact clinician optional, is this sufficient?
Control group going into HealthSteps lack of resources limited retention some features e.g. Red Flags

Online game-based youth mental health education program
Target audience:
young people aged 16-25, particularly young men.
Objectives:
Increase mental health literacy
Increase skills to change thoughts and solve problems
Application of learned skills to improve mental health
ROC Overview
Methodology
Single group, quasi-experimental repeated measures design (pre-, post-program and follow-up)
N = 266 (176 females; 88 males)
Questionnaires included:
K10 (depression and anxiety)
AUDIT (alcohol use)
Coping Strategy Indicator – short form (subscales – problem solving , seeking support, avoidance)
Resilience Scale – short form (RS – SF)
Satisfaction with Life Scale (SWLS)
Additional items examined drug use, mental health stigma, help seeking attitudes, program satisfaction and application of skills in day-to-day life.
Issues for Discussion
What is the minimal process considered sufficient for informed consent?
Are we overconcerned with privacy?
What are the minimal requirements for duty of care?
What is your experience in the transfer of measures to the online setting?
Should standard measures be robust enough to cope with minor variance?
How generalisable are the results from Internet studies (convenience samples)?
How can the generalisability be improved?
Can inferences be drawn from randomised controlled trials within convenience samples?
