3Adolescents as pedestrians
- Evidence suggests children first approach adult
levels of pedestrian skill at 10-12 years1 - However, peak pedestrian injury rates in UK occur
later, between 12 and 15 years2 - But, evidence on skills misleading?
- Transition to secondary school in UK results in
increased demands3 - Young adolescents regard road safety concerns as
childish4 - 1 Thomson et al, 1996 Tolmie et al, 2003

4Possible hypothesis
- Young adolescents overestimate their capabilities
in more challenging traffic environments because
they are less used to these - ie their perception of their competence fails to
match their actual competence - They pay less attention to the effectiveness of
their judgements, because they assume they are
able to cope - They make many poor or marginal decisions as a
result -

5Tolmie et al. (2006)
- Assessed actual and perceived pedestrian skills
of 11 to 15 year olds and adults using
simulations in four skill areas1 - Validated simulations against performance at
roadside - Found adolescents do not perform at adult levels
of skill under more challenging conditions - But, much more likely than adults or younger
children to over-estimate relative competence,
especially post-performance - Effect was restricted to 13 to 15 year olds, so
not simple function of transition to secondary
product of peer influenced disregard of risk? -

6Present study
- Does misperception of performance lead to
hazardous behaviour? - What attitudes and norms operate for adolescents
in relation to pedestrian behaviour? - Is risk-taking perceived as a positive
characteristic? - What is the relative impact of skill, attitude
and identity on pedestrian decision-making? - Present study addressed all these issues, by
- - collecting data from one sample of 12 to 15
year olds on all elements - - relating measures to self-reports of actual
behaviour (cf. Theory of Planned Behaviour
framework, Ajzen Madden, 1986)

7Methodology
- Computer-based measures of actual skill and
perceived difficulty as in Tolmie et al. (Session
1) - On-line questionnaire (Session 2), collecting
data for eleven target behaviours, some cautious
(eg waiting for green man) and some risky (eg
running through tight gap) - - attitude to, and intention to perform target
behaviour - - perceived approval of others, PBC, plus parent
and peer norms - - also measure of self-identity (Q-sort) and
general risk-taking1 - Self-report measure of subsequent performance of
target behaviours, plus accident/near-miss
history (Session 3) -
- 1 modified version of Attitudes Towards
Risks Questionnaire (Franken, Gibson Rowland,
1992)

- c.100 participants (n307) in each of three age
groups - - 12/13 year olds (S1)
- - 13/14 year olds (S2)
- - 14/15 year olds (S3)
- Participants drawn from four secondary schools in
West Central Scotland - Balanced for gender, full range of SES

12Summary of profile results
- Adolescents are in general positive about
cautious pedestrian behaviours, and negative
about risky - Perceived approval and parental norms follow very
similar profile - Peers are seen as substantially less
cautious/more risky - Self-identity/risk-taking profile lies between
parent and peer norms, and trend is towards
greater risk with age - Intentions and behaviour follow similar pattern
to identity, but behaviour tends to be less
cautious than intended, suggesting additional
influences at work - Averages mask considerable individual variability

13Regression analyses
- Given variability, what predicts less
cautious/more risky intentions and behaviour? - Separate regression analyses carried out for
intention and self-report of behaviour for each
of the 11 target actions - Variables entered in following order
demographics, intention (for behaviour only),
TPB, skill, perceived skill, norms,
self-identity/risk-taking - Results very consistent across target behaviours,
models account for moderate to large proportion
of variance (adj R2 .28 to .69 for intentions,
.17 to .43 for behaviours)

14Regression results - intentions
- Attitudes and approval are weak to modest
predictors of intentions (final beta .07 to
.30, .02 to .18 respectively) - Approval is initially stronger predictor for
cautious intentions (beta .09 to .35), but
values drop when norms included - Peer norms are initially modest predictors of
risky intentions (beta .22 to .30), parent
norms weakly predict cautious (beta .04 to .17) - Self-identity/risk-taking is strongest overall
predictor (final beta .20 to .65), and
influence of peer norms drops when this is
included - Parent norms are associated with approval (beta
.09 to .35), peer norms with self-identity/risk-ta
king (beta .08 to .37) ie effects of norms on
intention appear to be partially indirect

15Regression results - behaviours
- Intention is modest predictor, not always that
(final beta .05 to .20) - Peer norms predict risky behaviours (final beta
.03 to .23), parent norms cautious (final beta
.07 to .26) ie effects on behaviour appear to be
primarily direct (sheep-following vs established
habit?) - Self-identity/risk-taking is only modest
predictor here, and not for all behaviours (final
beta .01 to .28) - Risky behaviours were associated with near misses
(beta .11 to .34), and thence with accidents (r
.24) ie impact is tangible - Misperceptions of competence were more strongly
associated with self-identity/risk-taking (r
.14) than with behaviour (rav .03) - Skills (especially safe route planning) were
positively associated with more cautious
behaviour (beta .09 to .15)

16Implications and conclusions
- Adolescents are pulled towards riskier intentions
and behaviour by perceptions of peers, attempts
to be like them - Misperceptions of competence are symptomatic of
pull towards risk - Parental behaviour provides pull in opposite
direction, via modelling of safe habits, approval
of cautious behaviour - Support for parental modelling of safe behaviour
during primary school likely to be productive
intervention - Better skills provide a further measure of
protective influence - Training adolescents might be counterproductive
due to perception of childishness, but if they
contributed to training of younger children, this
might improve awareness of skill gaps
