Overactivity, impulsivity and repetitive behaviour in males with fragile X syndrome: contrasting developmental trajectories in those with and without elevated autism symptoms
Published in
Journal of Intellectual Disability Research, May 2018
Hyperactivity and repetitive behaviour are characteristic features of fragile X syndrome (FXS). However, little is known about the influence of autism symptomatology on how these characteristics develop over time. We investigate the profiles and developmental trajectories of overactivity, impulsivity and repetitive behaviour, in males with FXS over three time points spanning 8 years.
Participants formed two subgroups, those who displayed elevated symptoms of autism at Time 1 (n = 37; Mage = 16.32; age range = 6.61-43.51) and those who did not (n = 32; Mage = 8.43; age range = 8.94-47.49).
Participants without elevated symptoms of autism showed a reduction in impulsivity and repetitive questioning over time, whereas those with elevated symptoms of autism did not. Differences between the two subgroups in several topographies of repetitive behaviour emerged at Time 3 only.
These results further understanding of the relationship between autistic phenomenology and behavioural characteristics in FXS.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 May 2018.
All research outputs
#16,838,790
of 28,257,452 outputs
Outputs from Journal of Intellectual Disability Research
#1,051
of 1,686 outputs
Outputs of similar age
#181,846
of 344,563 outputs
Outputs of similar age from Journal of Intellectual Disability Research
#9
of 14 outputs
Altmetric has tracked 28,257,452 research outputs across all sources so far. This one is in the 39th percentile – i.e., 39% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,686 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.3. This one is in the 36th percentile – i.e., 36% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 344,563 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 46th percentile – i.e., 46% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 14 others from the same source and published within six weeks on either side of this one. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
